Love the program and been using this for awhile now. But since yesterday I have had a problem preventing me from using it. When I try to open I get this "unhandled exception has occurred in your application.." and at the bottom it says "cannot read that as a ZipFile" I hit continue and it opens the program but will not allow me to add a mod. When I click "add mod" it lets me choose the file just like normal but when I click it and try to open it the same exact error displays and doesn't add it to the menu. Any ideas? Thanks.
