I've reorganized the project, saved AS with reorganization slow and created new project, I've deleted and recreated the symbol table. I've also installed UpdateCollection 7 but that hasn't solved the problem either. I don't know what to do anymore... Attachment crash.zip (122 Downloads)

If your project is V7.1 SP4 or lower, you have to update with intermediate steps. See attachment and enclosed the software update manual.
