Hi Jeff, Mac,

If its any help... I now have one machine back up and running.

As mentioned after an install of 2014 in XP there is a problem in that will only mix down to mono. This stays with the machine if one tries to return to 2013.

I tried registry cleaners not knowing where the 'hook' was, but nothing positive. So I deleted Power Tracks, Band in a Box, Real Tracks and everything that looked like a remnant, even going into windows system and deleting anything that looked suspicious.

Gross I know but now I have Power Tracks 2013 up and running and rendering down to stereo on one machine. Probably a file in win sys that was doing the dirty work???

I will leave the studio machine as is 'cause a "lead technician" will be in Tuesday noon and "may" get to my case within 72 hours with a remote scan, (support, ha)
