DeltaP3D

So i was recently doing this flight KLAX-EDDP and i departing without a problem auto save was doing its job and 6hrs into the flight over the Atlantic my sim crashed (P3Dv4) i wasnt to worried knowing i have auto save i could just load back up into the flight but when i click on load scenario none of my auto saves were there not a single one it was all gone i was so furious and i told my friend what had happened to me he said the same thing happened to him thats why he quit flying for now and my other friend told me the same issue happened to him i am extremely furious i paid nearly $30 for this main feature and its not even working properly im scared of doing another flight i hope this gets fixed quickly
