Hi,
I’m relatively new to cryptocurrencies and have just updated my Zcash Swing Wallet. I am trying to send some Zcash but every time I click send, I get an error message which is as follows:
An unexpected error occurred when sending cash!
Please ensure that the ZCaash daemon is running and parameters are correct. You may try again later…
Unexpected response from wallet: error code: -15
error message:
Error: running with an unencrypted wallet, but walletlock was called.
I have been searching the internet for an answer to this problem for a few hours now and had no luck at all. Can anyone help me?
Thanks in advance!

Can nobody help with this? I have seen that many other threads have been resolved since I posted this and I haven’t even had a response…
This problem may happen if you have a mismatch between the versions of ZCash and the GUI wallet. It is a good idea to try using the latest ZCash 1.0.8-1 and the latest ZCash GUI wallet - 0.69

Hey thanks so much for your reply. I am running ZCash GUI Wallet Version 0.43 and ZCash Daemon Version 1.0.3. How do I update these to the latest versions without losing my ZCash (I read somewhere that updating can cause loss of ZCash).
I now have zcash daemon version 1.0.9 but cannot figure out how to update my GUI wallet. Can you help at all? Your assistance will be hugely appreciated 
To update the ZCash Desktop GUI wallet, just replace/overwrite the old ZCashSwingWalletUI.jar with the new one.

Despite still not fully understanding what I did, I seem to have managed to fix the issue. Thanks so much for your help, you are literally the only person who’s been able to make a bit of difference.
Do you have a Bitcoin address for donations? I have no Zcash left as the purpose of me getting my wallet to work was to send it all out.
Thanks again for your help!
