Copy Games w/o linking to Pc?

[Spectre_au]

I have evox and boxplorer.

I have copied games to the X-box HDD using boxplorer no worries. The games work fine except for a couple.

I have copied V8 supercars and The Sims to the HDD. When I goto run them (either by boxplorer or evox) the X-box reboots and goes back to the evox screen.

Anybody know what the problem may be?

Thanks
