This is a tricky issue because Automatic Train might not work for you depending on your individual computer. Testing shows that it works for MOST users but there are still a good number of users having problems. This thread will be dedicated to fixing AutoTrain issues.
For those familiar with web design, AutoTrain simply tries to do a time-delayed redirect using javascript or a meta-refresh. I suspect that most users having AutoTrain problems are experiencing interference with some sort of popup blocking software.
