Update: I just started the upgrade to v0.20.0 process now and found the mempool file in the appdata folder - which shows that the older BT core did not use a mempool.dat file. Wow.. I guess I'll check in in 2 weeks time - i had to delete all the files except the wallet in order to upgrade due to the forks and upgrades etc.. (estimated blockchain download) from Genesis block.

I think 0.8.3 is so old that it does not have the functions described such as abandon transaction. All I can do is view the transaction details (amount and addressee), or view transaction ID
I have checked with an old copy of 0.8.6 as I don't have 0.8.3... and it has the console available (Help -> Debug Window -> Console) and dumpprivkey works as it should:


Note: the first address is not in the wallet so "code -4" is the correct response.

If you are getting the "Private key for address XXXX is not known (code -4)" error, then you are most likely using the wrong address with the command... Click on the "receive" tab and then try the dumpprivkey command with one of the addresses shown there, to confirm that it is all working OK.

Figuring out which addresses in your wallet the bitcoins are actually on is going to be the next challenge... as they could be on change addresses, which I believe are not show on that "receive" tab. I'd probably be inclined to just use PyWallet to dump the contents of the entire wallet, extract ALL the private keys and then import them all into Electrum... and let it do the job of find which keys have coins Wink

I am quite sure I have the right address applied because I only have one address and I have been using this wallet / address for years

I also cant find the mempool.dat file to delete in the bitcoin programme folder (c:/program files/bitcoin). Am I missing something?

Thank you all for the replies. Let me give it the suggestions a try.

To answer some questions posted. I am the sender and the unconfirmed transaction is in my node history. That is probabl why my node reads 0 balance because it has the history that i've sent it out. I tried upgrading to a newer node before, but since a certain version of Bt core,  an upgrade required a complicated procedure that meant a reset of the blockchain download.. it'd take me like 3 months to sync up again. Which is nearly ehat I just did before committing that silly mistake, and that why I wanted to try Electrum - without syncing up

I accidentally sent all my bitcoin with 0 fee. I waited 6 weeks already and neither the receiving address nor my node shows the bitcoins.

I checked on the blockchain mempool and my transaction code cannot be found - most likely "forgotten"

I also checked the blockchain for my wallet's address balance and the online platform shows that that the missing bitcoins are there / should be in my core nodes wallet

So I am stuck - Without the transaction code I cant pay services to help process it. My node wont let me resend it because it shows 0 bitcoins.
My node version is very old - 0.8.3 beta so I cant do any RBF, PPFC etc. and I have been trying to transfer it to electum by dumpkey but it says key cannot be found error code -4

What can I do here?
