We turned off logging in v3.0, but are beta testing it right now. Some people are still having problems with the Windows version of TMC not working and we still haven't been able to figure out what the problem is. We do know it's a communications issue, but it could be one of many things. Unfortunately we are still not having luck with the few users that are having some unknown problem.
If anyone in NJ has a problem perhaps we could meet you sometime? We have not had the problem here in the office, so have been unable to determine what the exact cause is that is preventing it from working.
