For some reason in the last 1 week some of my AC21 updated pln files (these are legacy projects brought forward in many iterations of ARCHICAD) won't load. AC21 crashes after loading a library that I have warnings about being corrupted but have always .

The odd thing is that all the projects open successfully in AC21RC. I am able to save the projects as AC20, then open & resave as AC21 without any problem.

Anyone experience anything similar? Or have any idea what is happening?
