Has anyone been able to use the Torrent-Version of Ambitions on Wine and Ubuntu?

It works fine for Windows XP, but with Ubuntu, the installation failed (I got some error about the czech help data being corrupt). So I replaced all of my Ubuntu Sims folders with their Windows version. However, when I try to launch the game, I get an error message saying "Unable to start game, Server initialization failed (0x065d274)". According to the Wine AppDB, this error occurs if the game wasn't purcheased legally and offers no further advice except for buying it.

Is there a workaround or do I really have to buy Ambitions to play the Sims 3 without rebooting?

I'm using the latest version of Wine and Ubuntu 10.04.
