Gwx problem again

[Phila595]

Hi guys,
After some advise again,
On occasion when setting up a new game, once I've pressed start game, it starts to load up..........the loading bar gets nearly right to the end, then I'm informed program has stopped.
I have to start the game again from beginning, but this time the loading bar will go to the end and the game loads up, very strange....... has anyone any suggestions please?
Many thanks. Phil
