[philadelphia killing mach]

so i figured i'd reinstall mohaa to see if it would solve the problem i'm having after shutting the game down and taking forever to refresh my desktop. i first moved all my mods and skins to a new folder on my desktop out of the mohaa main. i then inserted the disc, used the uninstall option and then attempted to reinstall after rebooting the cpu. no dice. i got as far as it informing me it was going to download an newer version of divx for me. then...

Medal Of Honor Allied Assault_code.exe is not a valid Win32 application.
followed by
The registration number was not correct. Installation cannot continue.
(didn't even get to the registration key window with the boxes)
i ran regedit and deleted any remaining mohaa registries. still got the above.

did a search on the topic here and downloaded regcleaner, deleted anything that said mohaa or ea games in there also. still get the same warnings.

ideas ?
