You can find the files needed to overwrite in your client folder Exp: C:\Program Files (x86)\EA Games\7.0.11.2 Client\Ultima Online Classic.
Is mine but i have lots of diffrent #.#.#.# clients for testing reasons so yours wouldnt have \7.0.11.2 Client folder.
If your Running a 7.0.0.0 Client or higher 2 files will need to be diffrent from the above:
[Gumps.mul is now Gumpart.mul] & [Gump.idx is now Gumpidx.mul].
I was able to duplacate the issue. Seems your linking Fiddler to an older client. When you open fiddler you will need to link Fiddler to the Client files your changing.
1. Open Fiddler:
2.Click Settings at the top left side of App:
3.Click Path Settings...:
4.Click Set Path Manual:
5.Find the Client your changing:
6.Click Ok:
7.Then close out by clicking the small x box at the top right of the PathSettings Screen:
8.Now your ready to start replace the gump files.
If your Running on a system like mine (x86) or a (x64) You will need to get the right Fiddler (x86) or (x64) for your system.
All 3 Vers. of UOFiddler are
Here.
Note: Make sure to copy your *.muls to the right client Dir.
