Hint for all SOLO Miners:
You are missing ur solo mined coins ? Then propably this will help you.
Even if u only have
one receiving address, the DMD mined solo have another address!
So you have to reopen wallet v2 -> dumpprivkey from this solo mining address -> close v2 -> open v3 -> importprivkey from this solo mining address
ALL FINE

Maybe i am only having this problem. Then forget about it
