If iMD App (via the Lab Range application) is not working — login failing, downloads stuck, activation code rejected — the fix is usually one of ten known issues, and most take under five minutes to resolve. Work through this list from the top; the fixes are ordered from most to least common.
1. Login Error: "Account Active on Another Device"
The most common issue by far. Each iMD account supports one active device at a time. If you switched from your laptop to your phone without logging out, the new login is blocked.
Fix: log out on the previous device, then log in on the new one. If you no longer have access to the old device, message support on WhatsApp or Telegram — they can reset the session remotely, usually within minutes.
2. Activation Code Not Accepted
Fix: the code must be pasted into the search field on Lab Range's first page — this looks like a search bar, but it is the intended activation input. Check for leading/trailing spaces from copy-paste. The app closing immediately after entry is normal: re-open it and log in.
3. Database Download Stuck or Failing
Fix: this is almost always storage. UWorld and AMBOSS databases are large. Go to Databases → Edit, tap the red icon to remove the partial download, free at least 10 GB, and retry. On a slow connection, download over Wi-Fi and keep the app in the foreground.
4. Corrupted Download / Database Won't Open
Fix: press and hold the download button for 5 seconds to purge temporary files and restart the download. Still failing? Go to Account → Delete Temp Files, then re-download.
5. App Crashes on Launch
Fix: force-close the app and reopen. If it persists: restart the device, then check for a Lab Range update (App Store on iOS; re-download the latest APK on Android; latest installer on desktop). Outdated app versions after platform updates are a frequent crash cause.
6. Content Loads Slowly or Shows Blank Pages
Fix: check your connection first — some resources stream while others are downloaded. For downloaded databases, blank pages usually mean an incomplete download: delete and re-download that database. If a specific third-party platform is temporarily unavailable, that is typically upstream maintenance — it resolves on its own, and support can confirm timelines.
7. Credentials Never Arrived After Purchase
Fix: credentials arrive within 1 hour of purchase. Check your spam/junk folder first. If more than a couple of hours have passed, contact support with your order number — delivery issues are resolved same-day.
8. "Unknown Sources" Block on Android
Fix: Android blocks APK installs by default. Go to Settings → Apps → [your browser] → Install unknown apps → Allow, install, then toggle the permission back off if you prefer.
9. Offline Mode Not Working
Fix: only downloaded databases work offline — streaming content requires a connection. Confirm the database shows as fully downloaded (not partially) in the Databases tab. Also note the app needs to have been opened online at least once recently to validate your subscription.
10. Subscription Shows Expired but You Just Paid
Fix: log out and back in to refresh your account status. If it still shows expired, contact support with your payment confirmation — activation sync issues are fixed quickly, and your plan time is counted from proper activation, not from the glitch.
When to Contact Support (and How to Get a Fast Answer)
If none of the above resolves your issue, contact iMD support via WhatsApp or Telegram — typical response time is under 5 minutes. Include:
- Your device and OS version (e.g. iPhone 15, iOS 19 / Windows 11)
- The exact error message, or a screenshot
- What you already tried from this list
That single message usually turns a back-and-forth into a one-reply fix.
Preventing Issues in the First Place
- One device at a time — always log out before switching devices
- Keep 10–20 GB free if you use offline databases heavily
- Update Lab Range after major OS updates
- Don't share credentials — shared accounts trigger device-conflict errors constantly and violate the terms of service
