Ok so ever since the update on live this has been going nuts for me locking up, graphic corruption etc. Phoned THQ and they say I am only the second person to ring in with the prob, tried xbox live and the unhelpfull muppet on the other end said i have to delete game saves .... screw that ! so I had 3 saves one was a ghost lap, so iI deleted that, and I have a "global" save of 144kb and a save of 244kb. Can I delete any of these without losing what I unlocked ? If not, is there anyway of removing the update otherwise ?
