thanks for getting back to me!
Before I try this, now that I'm home with my PC I can be more specific about what's happening.
Basically for every program i try to open, a window pops up with a list of programs saying 'choose the program you want to use to open this file'.
Now, if I want to open IE and when the window posps up I select IE then it works. What doesn't work is when i try to access the programs, such IE, Skype, Photoshop, Windows Media Centre etc... from my little icons on the toolbar, and the same window pops up, it only has two options: Adobe Reader 9 and IE, no matter which one i select, nothing works.
Also if I'm opening Photoshop for example, it will say: 'choose the program you want to use to open this file' and then below it will have 'Photoshop.exe'
If I open IE, it will have iexplorer.exe (but if I access IE from the start menu it will say 'ssvagent.exe')
This is happening for every program I have...?!?
Do you think what you suggest might fix this problem?
