How do I uninstall VLounge? Every time I try to, it won't let me. It's telling me that it's unable to uninstall because the parameters are incorrect.
Install a new copy of Vlounge over the old one. Maybe you can uninstall then.
Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
