That looks like an error being thrown quite early in the process. One of the first sub-tasks when creating a UTM tile is the initialisation of the destination folder with the default files and the making of config.txt. After that, the next sub-task would have been the creation of the individual tile texture (which is independent of the 2D or 3D option). This, apparently, does not succeed.
My first suspicion here is that your instance of TransDEM might have a memory allocation problem. How big is your project? Are you running the 32 or 64bit version of TransDEM 2.5.*?
