Error running .cvs files in Excel

Can you please help me regarding .cvs files? If you scroll through it, the error will just pop up that says, "Microsoft Office Excel has encountered a problem and needs to close” and out of the application. My computer system has 2GB RAM with Office 2007 installed on it and some add-ons like Excel Visual Studio Design, Time Adaptor, Access Data Transfer, and TFC Office Shim. This only happens with .cvs files. I don’t want to convert the .cvs files to .xls, Can you please help me on this?
