Key already in use

Hey all,

Firstly, i apologise if this has been brought up by someone else already but i cant find anything about it.

Ive had my copy for a few days now as i work in a game shop. Obviously it wasnt letting me register the code until midnight so i waited. When it came i entered my code and got in no problemo, was playing for a few hours then went to bed.

Woke up this morning, went into uni, came home looking forward to playing then tried launching the game off steam again. To my surprise it asked me to enter my code again, i did so then got a message saying it is already in use.

I have tried re-installing, re-booting and all the like however it is still prompting me for a code again.

I just dont understand, i was playing it last night. Any ideas what i may be doing wrong?

Also, i tried unilock as well and the same thing happens.

Any help would be greatly appriciated, thanks.

I'm having the same problem, any advice on this?

Same problem I think.

me too cant believe i quit and try to start again hope it works sooooooooon

Same problem here

Kinda relieved im not the only one having this problem - As selfish as that sounds :S

Gonna try everything i can possibly think of, will let you guys know if anything works. Do the same if you work anything out. thanks.
