When I updated the wallet, I replaced wallet.dat in the new BiblePay folder with wallet.dat from the old BiblepayEvolution folder. If wallet.dat was missing, would my correct balance show on the Overview tab and with the command 'listaddressbalances'?
Also I am not sure why I am not listed on the Leaderboard. Boinc is running fine and my contribution history is shown on the WCG website. Maybe I should back up wallet.dat, uninstall the wallet and start from scratch?
What happens, when you manually do "sendgscc wcg"? Some days ago I had the same problem and with this I got the following:
"Error!": "Sorry, you must set up an external purse to send GSC transmissions. Please type 'exec createpurse help'."
Not sure why this happened, since I haven't changed anything for weeks and it always worked just fine. Anyway, unlocking the wallet and then performing
"exec createpurse help" solved it and I'm now in the leaderboard again.
