If Studio starts to render the file and then stops, the problem may be your Personal Firewall Software. Portions of Studio need to be able to access to your TCP/IP protocol to communicate with the RM.exe to render.
Most Personal Firewall programs (Zone Alarm, Norton internet security, ECT) will pop up a window and ask you if you want to allow the program to access the internet. In Studio's case please tell it yes, it will not be going out to the internet, only communicating with RM.EXE.
You can test this by unplugging you're the cable going to your cable modem, DSL modem or standard modem.
Once you give it the ability to access the RM.EXE through your Personal Firewall software it should render your project with no problems.
