I don't think you need to sudo to run it. I'd suggest removing all spring info from the registry as that error you get (window size -39) may be some borked settings in the registry.
I don't know how to clear wine registry, but i know how to clear all wine stuff:
That "rm -rf" is a powerful command, make sure you get that line right.
Also, try to run the windows lobby TASClient.exe on a writable partition. If you're running it straight from the windows ntfs partition, it will probably be mounted read-only and i don't know if the lobby likes that.
I have no problems running the lobby in wine and what i did was to download the full windows spring installer and run it with wine, installing the lobby in
~/.wine/drive_c/Program Files/Spring
And then i just run the lobby from the KDE start menu (wine puts it there).
