I am the person that started this thread. I have been in contact several times with MTU concerning this. The people at MTU are very nice. I have even spoke with Dave, The president of MTU, and that man really impressed me. He is very concerned about the crashing. Right now they are working as hard as they can to solve this problem. I don't know if it's due to some other program running in the background yet, but I have already tried two different computers. One with a 3200 AMD processor and the second one is a laptop Pentium 4, 3.3ghz processor, 512 mb ram memory, and a plextor 716 burner. Both have crashed.
So at this point I am working very close with MTU to get to the bottom of this. Remember MTU is the best program you can buy. So stick with it and I am sure MTU will work things out on this.
At this time I am getting ready to test run a new Beta version 3.104. I will let everyone know if this helps the problem of crashing.
I thank everyone for their imput. And thank you Dave at MTU.
