I've been mining using cryptonotepool.org.uk pool.
Now I try to open my wallet.
Seems like the simplewallet.exe just created a new wallet.dat for me. Anyways it asked my password correctly and the address is the same. But how can I access my funds. The monerod.exe just hangs forever and almost freezes my whole computer (v. 0.8.8.3). And the wallet complains that "Error: refresh failed".
Upgrade to latest version 0.8.8.4
