It worked for a short while, and then it started saying error executing application, invoking the filename of my mp3 etc.. So I tried uninstalling, but, it doesn't seem to uninstall proper either. Help

It still leaves the entries in the context menu.
Partially solved, I used shellexview to delete the registry entry, it was thinking the dll was in my temporary files since I ran the installer from inside of the zip file. Deleting that let me reinstall, and uninstall successfully, but, it does still give the same error about invoking. So, even after reinstalling it fails to work. I suspect there's more registry entries that need to be cleansed.
