Did you try to delete the wallet and data files? Can you create a wallet without problems?
I hope to release it within a month but I cannot guarantee that.
I deleted all folder and unpacked archive again.
It stucked on block 501 for a couple of minutes, then quickly updated till 1001 and stuck again, then updated to 1501, then to 2001. I guess I'd just need to wait for 20-30 minutes.
