Hi, I have an old PIVX wallet and decided to upgrade to the latest one. I have made backups of the critical files (as stated in the other thread). I've done it before when I've done the incremental upgrades of the wallet, and I've not have had any problems. Unfortunately, it's been almost a year and a half since I've opened the wallet, so I know that I am WAY behind in the wallet versions. I've downloaded the latest wallet, and downloaded the latest blockchain (removed all except Wallet.dat & Backups), and installed the latest snapshot. But now when I tried to start it, it says "error in opening the blockchain" and the client closes. Any help please?
