I installed v1.0.0.6 and had to rebuild the blockchain. It stops syncing at block 38015. I went to the roaming folder and deleted everything except the .conf and .dat files and let it rebuild again but got stuck on the same block. I didn't have this issue with version 1.0.0.5.
i have exactly the same...so dev, i think it was not good update :/
I got previous wallet, and all is fine now.
