I recently purchased actually two copies of Sound Taxi (two Different Versions one purchased along time ago and the other just yesterday) in an attempt to get the application to work under Windows Vista.  However, I have not had any success.  The applications continually cause Windows Vista to lock up.  In fact, it corrupts Vista to the extent that I do not even need to run the application and Vista will lock up.  I suspect it has something to do with a modification with the registry but I am not entirely sure.  Your Web Site at URL http://www.soundtaxi.info/music_answers/vista_drm.htm  hints to that Soundtaxi is compatible.  

My questions are whether Sound Taxi is compatible with Windows Vista?  Is there a Patch available for SoundTaxi to establish compatibility?  If there is not are there any plans to do so?  If there will be an upgrade, will it be provide at no charge to those who already purchased the package?  Where there be any limitations with the Vista compatible version if made available?
