MOHAA Spearhead install problem

[wikedclown]

I seem to be having some trouble installing the Spearhead add-on . I have installed the original game then when I try to install spearhead I get an error message that says "the registration number was not correct instation cannot continue" I have tried patches and reg fixes that claim to fix this problem and nothing seems to be working. Anyone that has been through this and has any ideas what I might be doing wrong please let me know.

If you bought the game then return it for another copy that works...if not then read THIS (http://www.fileforums.com/showthread.php?s=&threadid=27215) and don't expect an answer.
