I have a strange problem with VoxATC. I bought a serial to change my test version into a working one. Now VoxATC suddenly refuses to work. During the initializing hase of the VoxATC window, I hear the five voices ay "Test" one time, after that I get a "fatal error" and I am told to disable VoxACT. This didn't happen with the trial version.What went wrong?Bernhard

It would help to know which version you have installed but this error is typically caused by not loading a valid flight plan prior to initiallizing VoxATC. It is recommended to generate and save your flight plan and allow the flight to load and then launch VoxATC. If you are using the FS9 version try the demo flight again. If you still get the fatal error I would reinstall the software or contact VoxATC via their website contact page. Good luck.

This has been resolved. The problem was related to the installation of other scenery add-ons, not to registering VoxATC. Obviously the OP is so engrossed flying FSX with VoxATC X he has no time to post himself.
