ipad app crash

[EqnX]

since yesterday the app for the ipad seems to crash when i start is up. tried removing and reinstalling it (serveral times). the app then runs fine so i can sync but after that its back to the same old.
anybody got a clue to why ?

*edit, ik o got it back to work.. sorta, emptied my library and synced only 4 chapters (total sice about 40 mb). adding chapter for chapter and waiting till it crashes . anyone know if there is a maximum library size or somethin'?

greetings
