Hi. I have a problem with my bitbean wallet: blkindex.dat. What I have to do? Because I don't have access to my wallet
Seems your wallet did not closed properly. If a restart of the wallet will not work then you need to re-sync again.
Save your wallet.dat and delete the rest of the files in the BitBean directory.
This can be speeded up by loading into this directory a copy of the blockchain available on the web.
Always backup your wallet regularly and the whole bitbean directory (when the wallet is not running)
if you have the disk space.
