Re: [ANN][BTCZ] BitcoinZ - Low Fees, 100% Community, POW-Equihash No-Premine No-Tax

Same error here too :/
After deleting folders, and downloading again the blocks, it's works... until you close/reopen the wallet and the same error appear again :/

Hmm, no problem here. Closed it for an hour, reopened it, waited for synchronizing and it worked. But seeing the issues people have, they should look into it. :/

Yep,
My wallet is on Win7, Java is up to date. No problem before yesterday.

So, I try this command: "jre\bin\java.exe -jar BitcoinZWallet.jar -reindex" and nothing change... But Is it the good cmdline??? not sure.

-reindex argument is for zcashd, not BitcoinZWallet.jar.

Thanks NameTaken Wink

Running "zcashd.exe -reindex" reload blocks from scratch as well, but the problem remains after a restart...

try this one solution from telegram

[telegram] Hey, everyone!
For all who had a problem with not syncing GUI wallet (Swing wallet) there is a solution:
1). download a blockchain bootstrap from: https://s3-us-west-1.amazonaws.com/cryptochainer/blockchains/BitcoinZ_blockchain.zip
2) delete all excluding wallet.dat (!) in ../AppData/Roaming/BitcoinZ
3) extract downloaded zip file into BitcoinZ directory
4) start bitcoinz-wallet.exe (1.0.1.2) or bitcoinz-wallet.bat (1.0.1.4)
5) enjoy!
