wine users - Dec 2010 - Sims 3 crashes while loading town (Bug 18991)

Hey you guys,
ok I have been trying to get The Sims 3 base game running on my Lenovo L512 on
Ubuntu 10.04 for several months now and I just don't seem to be successful.
So I was hoping, maybe you can help me out on this one:

I installed it using PlayOnLinux (v. 3.8.8) which installs Wine 1.3.4, I run the
game on Wine 1.2.1 (since thats the working Version, see here:
http://appdb.winehq.org/objectManager.php?sClass=version&iId=16664&iTestingId=58209).
I followed all the steps from here:
http://www.playonlinux.com/en/topic-2530-Solutions_for_frequent_problems.html.

Everything went well with the installation but whenever loading a town the game
crashes to the desktop after loading like 1/6 of the bar. The bug is known and
reported here: http://bugs.winehq.org/show_bug.cgi?id=18991.
I ran the fixtz.exe from the bugreport to fix the Mono timezone bug and nothing
changed.

Can you help me out here?
Thanks a lot
Dominik

Don't bother using the launcher; bypass it and run the game directly,
a la

Also, you should consider just running the game with plain up to date
wine; the only workaround needed is winetricks d3dx9_36.

Oh, and the folder is Programme because Im german and running Ubuntu in German
:)

Wait, do I have to install Mono manually or does it install that with the Wine
installation?
PS: I ran the two-liner from your post again, no changes...still crashes when
loading a town
