if im not mistaken i think your EA desktop is now saved in a different place.
documents>EA Games>Ultima Online Legacy>user data>Account>shard>toon
if im not mistaken this new place to save them was instatuted a month or so ago.
so if the desktop you are wanting to copy is uber old, then youll have to go fetch it from C drive>program files>ea games>desktop>account>shard>toon
and move it to the new character uneder the first listed way.
but be sure not to copy the top file and bottom file of those toon files.
i cant recall what they are off hand, but i know that you do not wanna move the top one and bottom one, just the ones inbetween.
