Thx man.An alternative solution t this which i followed is what i said earlier if someone doesnt want to mess with commands.

Just patch the System/Library folder by selecting the last option from marvins AMD utility BUT before patching it back up the front row app inside System/Library/CoreServices.After that reboot and paste front row you backed up earlier int System/Library/Coreservices.

That will do the trick.

Nice feedback everyone!

maybe these solutions should go by the original poster as a workaround in the first page of the guide.
