Digital PS3 Download; Can't Access Multiplayer ?

Just bought this game so my friend and I could enjoy the co-op experience. Doesn't seem that multiplayer works though.

I registered a PS2 memory card at the dashboard, and even downloaded the PS2 System Data off of the PS Store to see if that was the problem, but an error keeps coming up, saying the "network hardware is not detected," or something of the sorts.

THq has flat out ignored my email; can someone please help ?! This is turning out to be a waste of money !!

I'm referring to FSW: Ten Hammers.

I was apparently redirected to this the RTS Games forum? Why is there no PS3 forum for the digital download of Full Spectrum Warrior??

Anyway, sorry; did not notice !
