You can download the WBB wallet from the WBB Wallet download section.
You must update to the latest version of the WBB Wallet. Please check in the wallet download section for latest version.
Always ensure you keep a backup of your wallet.dat file which is found in the %appdata% directory.
If your wallet does not get a connection and you are on the latest version please check in the download section and download the .conf file for WBB.
This file should be placed in the same directory where you have your wallet.dat file.
Yes, please check in the download section for the latest bootstrapp file. We create once a month a new file.
You only need one if you have never synched up the WBB wallet before. The initial loading will take time as the blockchain of WBB is growing all the time.
