I recently installed DirectRT on my laptop, but have had difficulty running the samples in your training - it comes up with the following message:


DirectRT can not determine your display's refresh rate which is critical for accurate timing. The cause of this problem is usually an outdated or disabled video driver, or disabled video acceleration in your video settings. If you need help resolving this issue please report this error to support at www.empirisoft.com. Error #6. Overflow


I am running this program on my Mac, via Parallels with Windows XP and all attempts to reinstall drivers have been met with reports that they are installed ok. I have attached a diag report, as suggested in your manual.


I am tempted to simply switch to your beta program for Macs instead of trying to run it through Windows - would it be possible to switch my license to this if you can't help me with the problem with the program?
See above for discussion regarding Parallels versus BootCamp and see if that helps.
