Will have a look into it, and let you know when I find out what exactly happened. My apologies for this inconvenience.
Edit: Ok it seems that there were problems in the recording of the battlerecorders, therefore the problem are the battlerecorder files itself. Not your programs. Shamefully we cannot recover them. With the next gamenight this problem is solved, and the battlerecorder files will be working by then.
Again, my apologies.
