I purchased pre-sale Ether and stayed on the sidelines until today. I downloaded the Win64 wallet installer from GitHub and installed on Windows 10. It's running and syncing to the network.
It has a drop-box for the pre-sale ether wallet .json file. I drop it there - enter the password, the import starts, the logo goes through cool graphics - then the wallet just crashes - disappears. No process left.
Any thoughts?
Thanks
