For those that have a problem, use that!
(Worked for me atleast)
(its the "laa_2_0_4.zip" zip file)
Unzip it, open it up, and then find your uos.exe and client.exe and if you use razor aswell, target that aswell.
The basic mode works fine, so no need to go advanced. If you see on that page, the basic mode opens up a window with 1. select an Executible (Where you need to find your client.exe and uos.exe, fastest way is to right client your shortcut of uosteam.exe and "open file location" or something like that, for client.exe, well try find your uodirectory, shouldnt be that hard, and find the client.exe!
