Backtesting with older builds

 
I cannot use my older FXT files with older builds either recently. (The ones which had the recalculate function.)

The whole system could be used like a month ago. The checker function in the FXTheader gives no error, when running it through the files. I even attached FXT collector, and collected ticks with that.

The result is the same, no matter what I do:
The tester zeroes my FXT file, and starts collecting data.
I've tried build 206,207,208, with recalculate off.

Anyone has an idea of what the matter could be? I am really stuck here...
