I had a similar problem some days ago http://ugx-mods.com/forum/index.php/topic,10865.0.html and now I ve noticed, where is the problem, but I cant understand why this didnt happen before, and I d like to know if someone can help to find a solution.
I can launch the game first time after to restart (normally) but if I am trying to fix an anim, for example, I cant launch the game twice in two minutes, sometimes I have to wait 5 or more minutes for game works.
If I remove T4M, I can launch game all times, but the problem is that I was working during months with mods that need T4M for work...
I cant advance with this problem.
I used debug view for can see exactly what fails and this is the report
