Did check all the assets and there build number was the same as or lower the 3.7. Checked my installation of Trainz 2010 and the same problem on there, now considering that I have not used 2010 for months I'm wondering how I could have the problem on 2 separate programs. Went to uninstall 2012 and was unable to as the uninstaller was corrupt and the same with 2010. I have managed to remove both programs and reinstalled 2012, and in the process of adding the patches but everything seems fine at the moment. Last weekend there was a problem with updates, one minute there was 300+ but wouldn't down load. Then the number dropped then went up again and at one stage it was reporting over 1000 so didn't bother. On Monday there was no updates, but yesterday I had the problem I listed above. Just wondering if the 2 were related.
