Thanks for the encouraging response. My computer specs are:
Intel Core i5 CPU M430 2.27GHz
Nvidia Geforce GT 330M GDDR3 1GB
RAM: 4GB
HDD: 500GB
Since I couldn’t make any progress with Windows 7 Premium, I upgraded to Windows 7 Professional and the XP mode, but whilst this at least lets me do some work it’s very slow and unstable and the video playback on both source and program monitor is incredibly choppy which makes me think it can’t read my graphics card. As one final attempt I’ll try and load in Win 7 Pro rather than the XP mode. Any other thoughts or advice very welcome.
Many thanks
