What version did you upgrade from? If it was a very old version you might need to grab the bootstrap and resync. But normally, if you are using an outdated version of the blockchain the wallet will not open until you update it. This is only if updating from the first wallet version. Are you updating from the first HYPER wallet?
Please keep me posted as no one else has reported these issues with the latest wallet and I want to make sure we can resolve this for you!
Thanks for the assistance.
On the new PC (Windows eight) I've installed Hyper 1.5.3.2 as a fresh install. Fully sync'd with 11 connection to the network and a new (empty) wallet. Everything looks good.
On the old PC (Windows 7) I'm using Hyper 1.5.0.0. That wallet has 12 connection to the network and sees my coins and transactions. This wallet states "Warning: Checkpoint is too old. Wait for blockchain to download or notify developers."
I copied wallet.dat from the old PC to the new PC and that's when I get the error. Everything looks OK until I unlock the wallet for POS. Then hyper-qt crashes on the new pc.
