I downloaded Nexus 2.5.0 x64 Qt wallet for windows and the blockchain. The wallet successfully accepted the blockchain but stuck at block 2203099. How to force it to sync at 100%?
If you are upgrading from 0.2.4.6 or earlier, this version will re-index your blockchain database the first time it runs. The process will take a while, up to 5-10x the normal load time depending on your hardware. Just let it load, then let it sync completely.
