IN THE APP Start with the affected screen
The source map cannot be loaded
Install the exact original difficulty and its audio in osu!. Check that it plays there, then return to the practice page and select Retry loading this map. An online score or another difficulty of the same song is not enough.
A practice attempt is missing
Finish a play on the generated practice difficulty, keep AimMod open, and use Refresh results in My coaching. Automatic result checks happen roughly every 30 seconds.
Check the player account and the exact practice-set version. An edited or replaced practice difficulty may no longer match the saved set. Older exports without tracking links can be reopened, but do not have linked section progress.
The original-map comparison is empty
Use the original difficulty, the same mods and scoring client, and complete several plays. Practice-section results are recorded separately. AimMod needs enough completed original plays before and after practice to make the comparison.
The wrong osu! client opens
Set Settings → Open and install destination explicitly to osu!stable or osu!lazer, then try opening the set again. If a file association in your operating system opens a different client, import the archive from the intended client.
An archived set has no Open button
Its generated files were cleaned up while its progress history was retained. Create a new practice set from the original map. To retain future automatic sets, favourite them or select Keep all sets in cleanup settings.
