I opened a question on support.ea.com 5 days ago. But they couldn't help me to

I was going to manually uninstall the game again, to try it with the instructions from your site. When i was browsing i found that the installed language from the sims 2 was  English US, and the languages from the expansions are English UK. Could that be the problem? I'm going to try to change the language from each till they all have the same with the instruction of this site: http://tg.sims2techguide.net/guide.php?g=13.

Edit: Didn't work, i also installed the game with copying the file in the folders. Didn't work to, maybe i'm going to do a format on my computer and see if it works after that.

Did you copied the files from both disks in the same folder? Because when i do that i asks me to replace compresed.zip, it's on both cd's.

Yes, i installed them to the default default directories. I already tried it without patches and with patches, but nothing changed.

Hi,

I recently bought The sims 2 Nightlife and The sims 2 Open For Bussiness. So i first installed The sims 2 + the sims 2 university, when i started university i could create a campus and go to them, then i installed nightlife, and started the game. On the main menu i got a message 'You have uninstalled Sims 2 University If you continue, your college neighborhoods.....', But the game was still installed. I was able to create a downtown from NL and i quited the game. I didn't know what to do so i closed nightlife and installed OFB. When i started it i got the same message but now it said that i had uninstalled the sims 2 Nightlife wich i didn't. I was able to add a shopping district.
I couldn't press on the buttons on top. i took a screen of it: http://img218.imageshack.us/my.php?image=expansionproblemlm8.jpg.
I now already reinstalled the game 6-7 times, still nothing has changed. I also did a full manual uninstall. I also defragmentated my computer, scanned on virusses and spyware. Turned virusscanner and firewall off, etc..
I hope somebody can help me.
