I dunno know if guys on here that knowledgeable about this on here but I have a question about a problem I'm having about my xbox but this is driving me crazy.

Whn I put a game into my xbox, it gives me an error message that says that the disk is in correct. I've taken out the disk and cleaned as it suggested and it still doesn't play it; the disk is not scratched up or anything either. Before it started not playing completely, it read "EVO" with a x below it and it would do like a system check before it started up and turn the butons green. But when the "EVO" thing showed up, the button would turn amber and not the usual green. Could anyone be so graciuos and help me out??

By the way, it's a "mod version" with the big hdd ($600).
