Hello,
I opened a tdm file three times. First time I got an unspecified error (2011-01-26_131854.png and 2011-01-26_131854.txt). Second time I got the error "handle is invalid" (2011-01-26_132602.png). Third time I was able to open the document. I didn't end the program until the trying.
I hope, this helps you to improve this useful tool. Perhaps you can analyse the problem, fix it or display a better error message.
Bye
