If your using Normal Burn of Skyrim it wont work, you need reburn it mate using The topology, C4eve released a Global Topology you can Use for ALL XGD3 "except Halo Reach Beta xgd3" So use XBC, inject the Topology file into your ISO of Skyrim, Reburn it has normal and Done, it will successfully work on New dashboard and 3.0, But because this is a Global topology it can not be tested and not 100% sure if safe online so i'd advice staying offline.. If you want be save online Rip the topology from your original Skyrim and Inject it into the ISO...
The options are up to you.. Me atm Using Global one because i don't want pull out my skyrim original to Rip the topology when Skyrim is single player and i might need reburn it anyway so just easier for me Burn it now, Keep offline and wait..
