Well, those are bad and good news at the same time.
Sad that your memory seems to be a bit to low to handle the ABB-Installation completely, but maybe we´ll still find a solution for you which will work at least. There are so many tweaks we can do, beginning from your screen-resolution up to the number of cars which will show up, Car-Details and so on...
But it´s fine that you now got all the content which ABB provides and you´re able to use it, even if you´ll do it on a different way as suggested.
And off course we can fully understand that you´ve got a live beneath GTL, hehehe... we all have a family, have to work, or maybe a yard which needs some attention
Maybe, for the beginning, it will help us when you´ll tell us a bit more about your PC, how much RAM-memory you´ve got, which processor is used on your Mainboard, which Grafic-Card you use and so on...
And I only can repeat it: whenever you´ve got questions, just ask. We´ll help you!
