Data lost for no reason

[exxaminer]

Hey, today I just lost all my data, when I . I Haven't reinstalled or updated my system nor the browser. It just happened out of the blue. Is it possible I crossed some boundary for file size or so? Is it possible that historical data is somewhere in there? I love my data and there is a lot of statistics I'd like to keep :-(

Interestingly - helper configuration remained intact...

Do you maybe have very little disk space left on your computer? If so, this happens automatically. The data cannot be restored.

Well I had like 10GB/10% of free space on my system partition, is that a little space? :-)
