Xbox Originals HELP!

Hi guys,

I just bought STUBBS THE ZOMBIE from Xbox Originals XBLA (My first Originals game), after a 2 hours download I find that it isnt WORKING!

I'll spare the details and go right into it, Can anybody help me get it to work?

I've got the Xbox Core System, a 64 meg mem card + 20 gig hdd (with a remaining 7 gigs after this download), I've tried playing when signed in and signed out and I have waited 20 minutes once for it to load, the screen just goes black...

I need help and Idea's, as this is very disappointing as Its my first chance to play the game, and If it doesnt work I lost $20, 2 gig bandwidth and afew hours of my life :(

EDIT: And yes I've updated,

also, in my save file there is a file unnamed with the tag GAME CONTENT in the Stubbs file, should I try deleting it or is it the update...
