Problems with re-Installing Medal of Honor Allied Assault

I am still getting the same error message when I attempt to Re-install MOHAA. This error is Incorrect register key.

I have used the uninstaller with the game, windows uninstaller, and Pro-uninstaller 2002.

I have deleted the following registry entries with no success:

{7914BE1E-F186-4790-B8F4-9F63C52A41C1}

{0DEA94ED-915A-4834-A87E-388D012C8E02}

I have also used the WinXP Compatability Wizard with no success.

I have used the EA Games E-Mail diagnostics to no effect.

The only advice that they have is to telephone the premium rate line at £0.75p/Minute.

Can any of you Gurus please help a desperate man.

Regards
