Thanks for the suggestion, but unfortunately I'm still having problems. I installed the latest version of DirectRt (2010.2.103.1115) on my Windows 7 machine. I am also running Medialab v 2008.1.33.
When I try to run the medialb file "task.que" (see attached), I get a black screen. I attached the files I am using (minus the sound file), perhaps you can take a look. I didn't attach the sound file.
I have a strong suspicion something is up with the way directrt is running on my office pc so I attached the dxdiag file for you to look over. I've been using directrt and medialab for over seven years and have a lot of programming experience with them. I've been encountering problems that I've never encountered before.
