Pretty URLs package - something gone wrong... may need to manual uninstall...

[Web Help Forums]

In installed packages it states I have this installed:
Pretty URLs   1.1.3

If I try to uninstall I get an error... that seems a bit odd:
"
An Error Has Occurred!
Although the package was downloaded to the server it appears to be empty. Please check the Packages directory, and the "temp" sub-directory are both writable. If you continue to experience this problem you should try extracting the package on your PC and uploading the extracted files into a subdirectory in your Packages directory and try again. For example, if the package was called shout.tar.gz you should:
1) Download the package to your local PC and extract it into files.
2) Using an FTP client create a new directory in your "Packages" folder, in this example you may call it "shout".
3) Upload all the files from the extracted package to this directory.
4) Go back to the package manager browse page and the package will be automatically found by SMF.

I would like to get the latest version:
https://custom.simplemachines.org/index.php?mod=636
to fix some problems with quotes in URLs
But I an not install this before uninstalling the older...

Any ideas of how to maybe manually remove all traces of old version of pretty urls? (Or whatever method that works)

[Shades.]

Would probably be best to ask the mod author in the mods support thread!
