Patch up your UO Clients all the way to over 7.0.43 +
Good to do this without us letting you know once and awhile so you can always see new hue, graphics, land etc. in game.
Head to your UO Folder where it is installed on your computer. Find UOPatch.exe.
Right click it >> Run as Administrator. Let it finish patching and close out of it.
I am also patching the game play files on server side.
