I tried copying the contents of the disk to my computer but my 360 XDK doesn't seem to connect to my PC anymore since I upgraded my computer. (Probably a coincedence, network was acting funny on my kit since I bought it).
And my original XDK's network is fine, but the DVD drive won't read anything :/
EDIT: Bit of a noob at the 360 XDK, got it working :P
Copying the contents of the disk now
EDIT2: All files copy fine except cyclotron.map, shared.map and waterworks.map. The copy dialog just hung when it got up to these files.
EDIT3: I managed to get cyclotron and shared (cleaned the surface of the disk really, really well).
I was also patient this time when running default.xbe and saw the main menu. Never thought I'd see it outside of a video!
