I have determined that the file is just corrupt. We were changing the orientation angle of some plans saved in the view map and when we saved one plan with a 90 degree orientation, all the views would then open with the 90 degree orientation. If we saved one view with a 0 degree orientation, all the views would then open with the 0 degree orientation. The odd thing is that the angle of the plans wouldn't change on the layouts (except for the view that was actually updated) so ArchiCAD definitely knew what orientation each view was saved with even though it wouldn't open with the correct orientation.
I fear the file is beyond repair so we are copying and pasting the corrupt file into a clean template file one story at a time. So far it seems to be working. Next we will copy all of our elevation/section notes into the new file. And then we will recreate the layouts.
If anyone has any experience successfully repairing a corrupt file, please share. I never want to rebuild a file again.
