I have DirectRT 2008.

When I try to select and run an input file, the task does not open. I wait for a few minutes and try again. A warning bar comes up that says:
"There is another instance of executeDRT.exe still running." But there is no additional screen or task visibly open.

I tried closing this using my task manager and also closing DirectRT all together. I tried restarting my computer. None of these have worked.

This has occurred on 2 different computers, of which the first will still not run DirectRT input files. This happens no matter which file I try to run, including the sample input files.
