Well, I don't know what error you've received, but since it's an RPM file, there's always the option of removing it with RPM:

In this case, (as root) "rpm -e ....." And, you'll notice that you've used a F10 version while you've got F11? Not recommended. Also, again with the dependency warning, I'd do the rpm --test before the rpm -e .
