MOHAA: Spearhead Installation Problems...

Everytime I try to install the FULL Spearhead which I bought today it says....

The registration number was not correct. Installation cannot continue.

When I haven't put any CD key in yet or anything. Does anyone else have this prob? AHHHHHHHHHHH I WANT TO PLAY!!!!

i think ea should wait a little while before releasing these games... they are my current favs, but there have been ssooo many issues, even their bf1942 v1.1 patch didn't address the most annoying/frustrating issues. maybe they know something i don't. anyways, i will buy the game but i am going to wait 'til they bundle it with mohaa, though you can get both at gogamer.com for around $55.
