Thanks
Do you have a screen-grab of the TDhelper window for when you are executing these command it may help in finding the problem.
[edit] on looking at the outputs you are getting they look normal to me based on your Laden/UnLaden entries?
This is more what I am talking about: http://gyazo.com/f252364aa2f9a369767a831cb3be9f8b
Have you tried running the command from a prompt outside of TDHelper? It looks like it might be a bug in TD itself. Maybe try reinstalling TD and see if it still happens?
I just finished reinstalling Windows(and python,TD,and TD Helper), and have been able to successfully replicate the problem. I do have it posted over in the official TD post as well but no replies to me as of yet.
