Fucked up something with the dash, need help

I had evolutionX dash and I was playing burnout when I decided to click on some xbox live link to see what it would do...I don't have a network cable attached so I didn't think anything of it. After I clicked the xbox live link it said it was updating and had a progress bar, so now I am stuck with it booting the original dash. I know my mod and everything is still there, but how do I get back to accessing the other dash?

Thanks, I haven't messed with this stuff for a while so I don't have all the resources anymore, but I do have the original HDD if i have to use it...wasn't planning on doing a hardware project tonight, just want to get back to burnout. Thanks!
