This has happened to me a couple of times already and the only way I was able to fix it was to open Appdata and find CryptoJacks folder, open it and delete everything except for the wallet.dat file, just make a back up of the wallet.dat file just in case. Once done open up your wallet and it will start syncing up again and should fix your problem. Now there is a site that has an up to date blockchain which should help speed up the process http://cryptochainer.com/dir/ but not sure if they can be trusted.
I have tried what you said but still it wont fix my wallet. I have to try the site you gave http://cryptochainer.com/dir/ to resync my wallet. This is risky but i have no choice. By the way mate how to get addnodes in cryptopia? Thanks
I'm sorry to hear that what I suggested hasn't fixed your problem as this has always fixed it for me when I lost power and had the same issue with the wallet giving me an error when trying to open it. Well I hope you can get it working again, yes it is risky but I have seen some devs recommend them so just scan the file once you download it. Now to get addnodes from Cryptopia, just go to their website and at the top you will see a tab Coin Info click on that and all the coins will come up. Now in the Search box type the coin you want and hit enter, now the coin will show up and then click on Connections and the Addnodes will come up, copy and paste them and you should be set to go again. Cryptopia seem to always have up to date nodes so that is why I use them all the time.
Hi Mate.. Im glad to say http://cryptochainer.com/dir/ help me with my syncing problem. My wallet is fixed now and staking. I will still copy the addnodes in cryptopia and paste in my cj folder so i wont be having a problem with my staking. Again thanks a lot for the help mate
I'm happy to hear that you got your wallet back up and running again. Now that you have it up and running I suggest that you make a backup of the blockchain each week like I have been doing just in case the power goes out again. It's simple to do just copy the peers.dat blk0001.dat database and txleveldb folders onto a usb stick and if you like also the wallet.dat file. By doing this it will save you time if this happens again.
