Save the file with the extension .caproj to the root of your folder project. This is the function "Save as" from your browser. (For example in FF in win7, click the top left "Firefox" menu and "Save as...")
If you don't have the option to change the extension from the save as option of your browser, save it as a xml (or provided extension) file and rename it afterwards directly from the folder.
Then open it from C2. It should work.Kyatric2012-02-05 14:14:12
