Cannot Register Simulator (404 url)

That's strange because I'm able to open things fine on my E: drive. I don't think it needs to be installed on the C drive to register the token or games. You should be able to open pdx bundles via CTRL+O anywhere, but when selecting them as a game in the simulator they have to be in the Disk->Games folder. You have to register the sim via wi-fi as mentioned by Will earlier to play games from the sim.
