I've upgraded the wallet on my Win10 64-bit PC from 0.10.3.1. Beta 2 to the 0.11.0 Hydra release. It hung up at 3442 blocks to go for a long time, then finished the download.
However, the $XMR I had in my account went to zero, and $XMR I've tried to transfer in from my Bittrex account didn't arrive.
Any ideas how I can rectify this? Thanks! Do I have to just delete everything from my PC and start again, backing up using my private key?
