Please help,
I have purchased Spearhead and it won't install.........at all.
I get an Error message saying :

medal of honor allied assault spearhead_code has caused an error in <unknown>.
Medal of honor allied assault spearhead_code will now close

Then upon closing this window i get a new one stating:

The registration number was not correct. Installation cannot continue.

What is going on?
What registration number? It doesnt get that far as to need the PIN code so it can not be that............
