C'est bon j'ai retrouvé mes données )

Mon post:
I made a mistake when I upgraded to 2.3f, and am not sure what happened.
It seems that I've overwrited "mzmanager_football.dat". 
Now, this file is = 1Ko
The same hockey file still = 1766Ko, I knew that my football .dat was more than 2Mo.
I've browsed my disk but no trace of a bigger than this 1Ko.

I don't know how I could recover my "2-hard-work-years" football file? 
I've also made a system backup but my file is not come back   

La réponse:
There francis always be backup files like mzmanager_football.dat2, .dat3, .dat4, .dat5, and .dat6

You start from .dat2 (latest) until you find one which is big enough (~2MB) and then restore it by copying mzmanagaer_football.datx to mzmanager_football.dat

Remember to do backup og files first.

if your backup restore didn't work, then you might have restored in a different folder ?
