Please help, I have been using impression for some time on my pc (vista-32bit) no problems. I wiped the pc and loaded windows 7 (32bit). When reloading impression on to the pc an error message pops up "graphics card does not support shader 2 and requires min 54mb card .... .... ...) the pc setup is no different to the vist setup (graphics card 8800gtx - so more than ok). Can anyone help. Cheers.Lee
