Hello,
I have a problem with Archicad 15 (Archicad 14 I went without any problems) When I run the AC 15 with a trial version so that freezes on the initial picture. The software and hardware in the PC I should be fine. I have windows 7 ultimate - i7 processor 2600, 8 gigabytes of RAM, Graphics AMD Radeon HD 6800 series. Where can be a problem please, thank you for the advice.
