Hey guys,

 My MSRD works fine, i can run all simulations and have even build some weird little machines, but I cant get any of the challenges to work. The urban one fails when before it gets all the way started, and the sumo one wont do any thing but make my computer beep after it starts running. Any suggestions? Im using july ctp

I suggest a complete uninstall of the Challenge Kits and of MSRDS and a fresh install.

Unistall the Kits, uninstall MSRDS, rename or move the MSRDS folder and them reinstall MSRDS and the Kits... if not works, send an email with the bug repport...
