Hi John
Looking at the output text I think you have a couple of problems with your PC...
1. your license is missing
2. the xml in your user.config file is corrupt
In theory the new system cleaning tool should cure both if you tick all the boxes to remove everything, then reinstall Videobox.
Who knows what else is corrupted on your PC, try to get the PC or Windows fixed if it has a fault.
Anyway try the above first to see if that helps you.
