The format of the results provided by our data sources (the PowerBall server and the NY Gov server) has changed ever so slightly and, as a result, slight modifications to our wallet source code were required. The changes can be seen in our Github repository.
As a result, you will need to download v1.0.8 of the PWRB wallet at the link below. This is a mandatory update as v1.0.7 wallets may fork during the next bet winner payout (as they're reading results from the PowerBall server that are in the old format and won't see the bet as a winner - basically, they'll think someone is trying to hack the chain and the PWRB security measures, that work so very well, will cause them to ban wallets paying bet winners that really are valid).
Please download as soon as possible and let us know if you encounter any issues.
