What do you mean with "I tried to uninstall" ? Have you got errors there ? If yes, which ones ? Or, do you mean you tried to uninstall it manually, by wiping the files yourself, which clearly should never be done.
Because, of course, if you ran the proper Uninstaller which, as in any other Windows program out there, is in the "Program and Features" section of the Windows Control Panel, it would have of course restored the default jetways as they were.
