Yo, why you patching your Ish? after EUO is squared up and patched, just run UO.exe from the folder directly. until the patch is a must, you never will have to patch...Just sayin'. I too rookied this problem, but not anymore. I have two folders, one is always patched so I can try out the new content when it's time. the other is one patch behind, so i can still Easy my way through UO.
Cheers,
Xander
