Computer is a Dell XPS M1530.
I just opened my laptop for the first time in a month and when I went to open Microsoft Excel 2007, I get this message: "This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel." I alse get this message when I try to open any other Microsoft Office programs. And when I try to open something such as Yahoo Messenger or The Sims, I get a message that says: "C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll could not be loaded." Any help with these problems will be greatly appreciated since I go back to school in a week and need these programs. Thank you.
