I am running WinXP pro SP3 .. (exactly the same O/S as before)..
I also changed the m/board to :- Asus EAH4350 SILENT (1GB). and added 4 GIG of ram..
Everything else seems to work..
I went to Cyberlink site, but as I didn't buy the programme from them they don't want to know! It was on the original PC I bought from a friend, complete with an install copy of it on the back-up drive..
Can anyone help please??
