I already read this but it just solved the probs with premiere.
The Problem in this case was that (so told me the german adobe support hotline) CS5 ist not working with mobile versions of the nvidia quadro 8in this case quadro fx 2500m).
I solved the prolbem by modifying a non-mobile driver. Now, some energy-saving features won't work anymore and it ist not an "offical solution" and it ist on my own risc of course, but it works well so far.
Just follow the steps posted in that link
I hope this will help some of you guys.
@mad*: that url is not valid anymore. do you have another link describing the steps for fixing the driver for quadro 2500m? thanks
Nvidia driver version 182.15 (Vista, 64-bit, unmodified) seems to work well with CS6 on Windows 7 on a Dell M90 with Quadro FX 2500M.
