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? christian@estlcam.de

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 https://drive.google.com/file/d/1wMDfzUIIH6lxOjPZSIwsxmAaSXJVF9n1/view?usp=sharing

Thanks all, problem sorted!
