Hi thanks for the reply!
I did just what u said, deleted all existing PRO files (compressed and decompressed) and cleaned my cache and everything with the latest version of CCleaner before reinstalling.
Unfortunately it still did not work.. the exact same error occured, i was unable to overwrite my previous moves. Now my smeargle is lvl 81, and can only learn 1 more sketch by lvl up, but i need 2.. help would still be much appreciated!! :)
Greetings Lemonlarry
