After the daemon has synchronized with the network, issue the save command in daemon console to store the blockchain, then you will be able to refresh the wallet
I have the same problem with my older wallets, the
save command does not solve the problem.
I have different wallets:
name1.bytecoin.wallet
name2.bytecoin.wallet
...
I updated my wallet sw on Ubuntu Linux from version 0.8.4.290 before to 0.8.5.306 now.
A freshly created wallet works fine. But if I run simplewallet with an older wallet I'm getting the error as shown above:
Error: refresh failed: transaction extra parse error. Blocks received: 6321The blockchain download is complete, of course.
