Hi there... I am running Parallels 6 on a Macbook Pro with 8 gigs of ram and the latest OS and Parallels updates installed. When I run my Soundtaxi application in Windows, I get a Media Player Revocation and Renewal error. According to Soundtaxi support, the problem is caused by a 3rd party app. They provide a way to see which app is causing the issue and sure enough, it ends up being the 'prl_hook.dll' file running within Windows. Google hasn't turned anything up on this. Anyone have an idea??
