I just noticed that there were updates at the Tascam site, so I downloaded 3.63, installed it and tried to open it in Sonar. It appears to load but the GVI interface won't appear so it's useless. It WILL appear as a standalone, but not in Sonar. I went back and downloaded and installed 3.62 and everything works fine with that update. I was updating from 3.60. I don't know if 3.63 has a problem with Sonar or if it's a bug. Anyone out there have any success with the latest update and Sonar 6.2?
