Internal Error 12024, 18652356, 18692061 and 18514761 during reopening a FM12 file

Hello everybody,

I can not open a FM12 file, the internal error code 12024, 18652356, 18692061 and 18514761 tells me nothing and I unless searching for a plain text translation for the error codes! This kind of trouble occures from time to time but now, first time on FM12. Therefore I try to check if my EDD rules producing this mistake, error or other undefined loop. I like to fix this error but I need to know where is the mistake, one week of work are be in danger in this case... !!!

Anybody a idea to fix this issue? (no *.Backup / *.Recovery file existing)

Any possibilities for "OPEN IN SAVE MODE"

Any possibilities for "CHECK FILE BEFORE TRY TO OPEN"

I can not believe that Adobe is unable to define plain text error codes, the technical support in unreachable!

Thanks for help,
