More Problems: Can't add friends, Can't use party chat

[Blackethergaunt]

I got the actual game to work, but I still have a few issues
First, party chat. Each time I form/join a party I get a 'unable to join party chat message' I searched for solutions in the forum, but I can't move the folder because Vista is being ******** and despite me being and administrator on this computer it thinks I don't have enough rights despite the fact that I did give myself rights to the file.
Secondly, I can't find userpreferences.ini. I tried searching with the search function, nothing came up. Now as Vista search has a habit of sucking I checked the folder's manually. Didn't find it.
I also heard it's possible to turn off the **** about asking about rights. This true? If so, how?

My other problem. Can't add friends. Each time I try I get an error message like this 'couldn't add friend due to unknown error. Error code /122' not sure about the precise verbatim, but along those lines.

Edit: I found a way to disable the stupid editing rights whining by Vista.
I also moved the game into the games folder from Program Files as advised here

Still can't find Userpreferences.ini.
I wonder if my install is faulty. Maybe I should reinstall, maybe even get a new download.
Haven't found nothing of use on how to solve the Friend add error code.
