In case you are operating a fire wall you may experience problems patching.
One of these problems may include the following line of events:
1. You start up the game and it attempts to patch.
2. Your firewall interrupts the patch session and asks you whether you want to allow that download.
3. You say: Yes, I want that download.. but it won't actually take up the patch session againShould that have happened to you the only way to resolve the problem is uninstalling the game, re-install it and disable your firewall before starting a new patch session.
I think there is another possibility to download the latest patches from www.uo.com directly and copy them into the patch folder.. But I am not 100% sure about that one.
