I told you I was a bit thick!!! I am trying to load a program and I get a message that .Net framework is not working. I did scannow and I have problems that cannot be repaired. I am having other problems which I think are OS related. Adobe 9 has stopped working today. I have scanned for viruses with Avast and I have Reg Fix 7 loaded but it doesn't cure my problems I bought Uniblue Powere suite but I had to claim my money back because I couldn't load it, this is when the .net framework problems surfaced. I am beginning to think I might have to go for a complete reload of Vista, but again I don't know how to do it. The computer didn't come with a Vista system disc I had to create 2 factory reset discs. All my main files are on a separate hard drive. I back up once a week.
