I have the same problem with Archicad 10. It takes about 5 to 10 minutes
to start. I even re-installed Windows, but no effect what so ever. The program worked very well for about a year but recently windows crashed. Since then I can't make Archicad 10 work properly. If I double click a pln. file, about 5 crash dump files appear and then the program doesn't start.
Do you think it's in conflict with another program or I should update some drivers?
hope you can help me.
