Download the Pcm.Daily's 2011 Db and run the .exe .
When installed go to options and choose for the pcmdaily2011 db.
And then you can play with those nice bikes.
Have you patched your game right ?
Maby this would help:
1.Uninstall the game an remove every folder
2. Reinstall
3. Patch to v. 1.0.4.1 ( because 1.0.4.2 sucks )
4. Install pcmdaily db
5. chose the db in options
6. Enjoy
