URL Rewrite upgrade error - Error (ERROR_BAD_PLUGIN) : Unknown module version 1.1.18

Hi gang,

I'm a novice, so my apologies in advance if this post should be elsewhere...

Up until now, Galler2 has worked well. This weekend, I went to Site Admin and upgraded the system to 2.2.5 ... everything was fine, until I tried to upgrade URL Rewrite, which had be 1.1.13.4. I received the following error (and now, the URL Rewrite & Permalinks no longer work).

In advance, MANY THANKS for any suggestions or help!
