invalid product key
Posted 16 June 2013 - 11:55 PM
So i bought GTA 4 Used from Amazon, installed it, etc. I can play offline, but when i go to 'Live' and log in, it says 'product key not valid. enter a valid product key.' I already have entered the key exactly as it is on the manual.
I've googled this and found a 'solution,' which didnt work for me.
Please help, thanks in advance.
