Now it seems like the pools block unlocker is stuck.. and therefore not sending payments anymore (probably due to pool config).
I upgraded to v1.2 again and the pool wallet is working.. but not my miners wallet. I don't understand why, I used the same upgrade instructions on both. I tried importing the privkey into a new wallet and it still shows empty.. The only difference is that the pool wallet runs 24/7.

I think I will just continue solo mining until there is a verified by dev pool config because every day there is a problem.
