Flodner, it appears that you are on the wrong chain, since we are (time of writing) already past 382420.
I suggest you resync (with bootstrap file to speed it up and the latest wallet).
Ok, thanks, will try it
I'm not very technical person, and I was waiting for new wallet update (which I hoped will solve this case) but 3 weeks or more passed, so I would better try to fix it and will continue staking and earning some MAG
