ARCHICAD 20: Open GL 3D blank

[Anonymous]

Help...........

I've seen dozen of threads like this but none of the solutions has worked for me.
All my 2D views look fine.
Everytime I go to 3D it shows up blank. If I marquee everything on my model and hit F5, it shows fine. As soon as I hit F5 again, everything is blank.

I've tried this file on multiple machines and same issue.

I can't afford to lose a whole's day work for a back up.

Any tips would be much appreciated.

OK...crisis averted.

Turns out there was gsm object in my embedded library that was causing this.
I deleted this object and viola everything back to normal.

Weird.
