My forza will not work HELP!!!

My Forza will not work I get to the title screen (the orange McLaren with the black background) and I press A but a message appears saying load failed an unknown error has occurred please try again later.

I have spoken to Xbox support they told me to power cycle my Xbox. Exchange the game for a new one. check my connection. reset my profile. Uninstall and reinstall but none of this worked.

the last support member I spoke to told me to come here and post my problem here. she said that a Forza employee would help me.

HELP!!!

This probably doesn’t contain anything that CS hasn’t put you through up until this point, but while you wait, here’s some reading just in case:

Yeah, I’m having the same problem. This is pretty lame.

You have to reset your console to default settings & then start the whole reinstall process for all your games again. You will NOT lose any of your progress on any of your games & non of the content you’ve created, ie, tunes & paintjobs.
I spent 2 weeks going through the whole fix process with ms support & also some help from here too & after i tried everything else, including what you have done, this was the only thing that worked & as far as i know its been 100% successful so far with others who have had the same problem.
It’s a ball ache i know but it does the job.
