Data erased

So when I started beamng, I realized there was something wrong, the unit system was in Mph (I use it in Kph normally), and there where activated some mods that I deactivated long ago, anyways when I got into statistics, It was only the last 15 minutes since I got into the game, and all the last months progress was erased, but another weird thing was that the career mode progress wasn't affected at all, so I would be really thankful if someone could help me with that problem...
