If you are not making progress, just try resyncing. Delete %APPDATA%/Zcash (backup your wallet.dat first if you have funds) and then restart zec-qt-wallet. ---

Ok, here we go… ! Watched block 1 begin downloading with 1 connection. What a beautiful sight. Now, do I simply replace wallet.dat file with my backup to retrieve my balance? ![image](https://global.discourse-cdn.com/zcash/original/2X/b/be07246472ea91756f7da71ea5ef0052eaeb12c3.png) ---

Replacing the wallet.dat file with a backup file most times work but i have encountered problems (in general and not ZEC related!). Problems can happen on various occasions, some general code change, fork, whatever. In case you hold the private keys i always would go with importing private keys as it’s just the best way in my opinion. Nowadays i keep the wallet.dat file backups just as last solution for the worst case if everything else fails for some reason. In case you have the private keys what you should: Under File ==\> Import Private Key you can add them all at once in case you have more adresses with funds, no matter if Z or T adresses. ---

THANK YOU, ZCASH COMMUNITY. I’m back up and running. I’m so grateful for your support. ---

So, you are saying, instead of replacing wallet.dat with the backup version, i could import my private keys. The private keys are associated with my balance accounts, thereby giving me access to my balances (just like replacing wallet.dat with the backup version would do). Am I understanding this correctly? Thank you in advance. ---

Yes, and in my opinion it’s more secure, faster and in most cases easier, enough you don’t have 200 adresses with 200 private keys. Have in mind that each adress has it’s own privatekey!!! But as well always keep a wallet.dat file backup somewhere. At least that’s what i’am doing. ---

Hello, again! So, I upgraded to zec-qt-wallet v0.5.11 and my zcash node flopped… i see this error: ![image](https://global.discourse-cdn.com/zcash/original/2X/6/69a4337ed3e9db46c1d127ad3a68ba28d5ee8c3a.png) I also ran zcashd on its own and received a similar error.

Maybe your db has become corrupted? Try restarting zcashd with ./zcashd -reindex [Previous page](https://forum.zcashcommunity.com/t/zec-qt-stuck-at-block-468824/32582.md?page=1)
