I couldn't get my currently installed version of Doit.im to start at all today. I tried downloading the new version 1.5.9 but that said it wouldn't install. "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package." I searched the forums for anything on this, but when I tried the solutions offered to people back in May, it didn't work. When I right-click the .exe file, I'm not given an option to extract.

Please help? The reason I paid for the PRO version is so I would have a fully-functional platform that isn't reliant on the web. This is VERY important to me. Thanks! :)
