Chovy-sign corrupted my base game?

Tried to use chovy-sign to get some iso's running, converting pump it up zero and audition portable. Both games works fine, but the game that i used to dump the license (DJMAX PORTABLE 3) now shows a black screen after opening this one from the home menu. Already tried refreshing licenses from vitashell but that doesn't fix it. Can this be fixed or is it forever doomed to be a slave for the other games?
