so i can´t test "getblockhash" and also can´t give you the output of "getpeerinfo". So i start to dowload the blockchain again. At the moment i have 52% completed and a lot of already confirmed transactions, but nothing happend at my balance. Balance, stake and unconfirmed stay all together at 0,00.
Once you are fully synced, try running
repairwallet in the debug console.
If that doesn't work, try the
-rescan commandline option.
Note that if your tx was orphaned due to a fork it is likely that coins you mined were also on that (invalid) fork. You won't be able to use those once you are back on the correct chain.
