Hello el-Odysseas,

Unfortunately, without knowing exactly which modifications you made to your songs and which song it is failing on, it will be very difficult for me to provide any information. If the merge just fails like that, it usually means it encountered an unrecoverable error, so it's exposing an error of some kind in MobileSheetsPro. It can't deal with something in your library now for some reason. It looks like the failure is during a merge of one particular song - can you tell me exactly what you modified in that song?

Thanks,
Mike
