EstlCAM problem... tools.dat

A new problem when opening EstlCAM arised this morning…when I launch the program, I got this error message, which basically states that there is a problem saving/opening the tools.dat file, and the expected result being my tool list is gone everytime i restart EstlCAM, when all the other settings are still her…
Any suggestion?

Maybe try emailing Christian with that question?

The Tools .dat file has become corrupt! Copy the Tools.dat file back into the specified location.

It strikes me that if the file is corrupt he doesn’t have a file to copy back.
If it helps I have uploaded a basic default tools.dat file

Thanks all, problem sorted!
