I recently upgraded to the Platinum Edition but have now noticed that I am having difficulty getting my AI Trains to remember their instructions. Basically, they just sit there. I am new to the game and so I admit its probably something I am doing wrong, but I had them working before the upgrade so I'm wondering if its related?

Welcome to the forums, Phillip.
It could be related, but it could be other things.
Open up the driver message history on the left by expanding the message queue. It's a small arrow just above the driver's image.
With that open, manually issue a driver command such as a drive to (some destination) located down the track apiece.
If there's an error, such as track missing lever, or path not found, you need to drive the track yourself in that direction very slowly and search, or better yet, add some in between track marks and have the AI driver drive to one of those. If that works, repeat the process for another command until you find the problem.
With that said, you'll eventually stumble on the problem, usually via a derailment!
There are, however, some issues with the AI being stupid. You can try setting junctions ahead of the drivers and ensuring the signals are green for the driver. Once set, CTRL-right-click on the consist and choose continue schedule - you may have to issue stop first, wait a minute, then continue-schedule.
Keep in mind too that Platinum has the pause enabled when jumping from Surveyor to Driver. This means that nothing will move until everything is unpaused.
Hope this helps.
