I love these sales!

Me and my friend decided today we were gonna game some MP Bioshock 2 .. placing my disc into my drive i noticed it didnt work... horrified i put theme hospital in which worked fine.. upset because one of my favorite games is broken .. i started idly clicking through the steam store .. then i see it .. Bioshock 2 for £4 .. thank you god!

Could you not of done 'Activate a product on Steam' and typed in the game key? I did that with UT3 :o

i hate these sales... i used all my money
