File won't open, cause Painter crashes.

Hello
Have been working on a file for a month or so, saved it yesterday evening for the last time, and now today it crahes substance painter on open. Auto Save done earlier crashes. A early version done 20 days ago crashes. (and din't crashes before, since I closed it, opened it to keep working).
Have tried to open simple file and they don't crash. 

File is pretty heavy and a bit messy, or can it be besause I imported Bitmaps to the shelf yesterday evening?

Also I gat update avaible message this morning on startup, but cannot upgrade since my hardware is too old.

Any advices vey much welcome, I don't have backups of this work.

OK now it's opening. (while I was posting here).
I tried 5 time to open it and it crashed, now it is opened. Cool, odd but cool. Maybe let painter load for few minutes?


Maybe keep this post for someone would bump into same situation.
