So I bought GC2 Gold brand new. I installed it just fine, started up Dark Avatar and entered the serial key (there was only one on the case) and watched the intro movie and tested out a sp game.

Then I decided to watch the Dread Lords video... double clicked that and entered the same serial key... and got "invalid product" error. What gives? There was only one "GC@ Gold" serial key!

Having something that's bugged will keep bugging me until I fix it.

Any ideas?
