Consist Creator Crashing

In the years I've been playing this game If there was a problem I could always find the solution, but this one has had me stumped and very aggravated for some time now!
My consist editor will load fine, but the moment I select a piece of rolling stick the whole thing freezes and gives me the "system temp dump or whatever"
This problem showed up out of the blue, I went trough all of my assets, trial and error to see if one of my rolling stock items was causing the problem, but no matter what I removed it would still crash. I eventually broke down and reinstalled the game, But that still did not fix the problem! I've looked on a lot of forums, and have gotten a lot of advice, but still the solution has yet to come up. shm, its a shame DTG cant even help because all we get from them is an automated email. Any one who can help please!
