Hey there. Long story short. My computer was getting blue screened none stop and while I was attempting to fix the issue I finally received one final blue screen of death. At that point, I had to do a complete fresh install of windows. As a result, I lost a lot of files. I downloaded bisq and my computer seems to have saved several previous JAR files and I do have one signing key file, but I can’t seem to get bisq to recognize that I am not a new user. Is there anyway I can get my verified bisq time back? ---

I seem to have resolved the issue and been able to recover the wallet but now I am getting an error stating that Keypairmust not be null. I have been able to restore both wallets I had on the account and the transaction log is populated, however, when i port over the backup wallet things get weird. My balance will show in the account but I am unable to purchase or withdraw any BTC due to the keypair must not be null error. I had no open transactions at the time. I have restored my payment accounts without issue, I checked to see if i could potentially buy btc and I had no problems. I then replaced the sig key without issue. Again checked to see if I had problems. The issues arise when I try and port over my wallet information. I have tried porting the entire BISQ folder which leads again to the error. I have also tried just porting the Wallet folder which still leads to the same error. In both cases, My balance shows but I am unable to trade/buy or withdraw the btc in the account. ---

Hey, instead of importing the wallet into the new data directory, can you restore it using you seed words? This may resolve your issue! ---

I attempted that but the balance of the wallet would not show. I’ve uninstalled and reinstalled bisq several times. I first tried using the seed words and had no success. Next I tried porting the entire bisq backup. That worked at first, but it showed my balance as an incorrect amount of BTC. I then proceeded to Port various wallet backups 1 by 1 until I found one that was the closest to my previous BTC balance. Currently I am debating on whether I should cmd + e the funds out and just make a new bisq wallet. Port the sig key and the old wallet information over and then transfer the funds back in. Any thoughts on this would be appreciated 🙂 And thank you for the reponse! ---

Currently trying a seed recovery again. I tried to cmd + E my funds out and it wasn’t working. Fresh install + seed reocvery = Restart Currently waiting for the bisq to sync with the mainnet. Very slow 2% and counting O\_O ---

@BisqM Hey, how did the fresh install and seed recovery go? Any luck yet?
