What can I do if I lost my Wallet password?

First of all, we are sorry to hear that. So far, there is no password restoration mechanism in a place, so we strongly recommend that users remember or write down passwords and keep them in a safe space.
The only way to get access to BitTorrent Speed again is to install it from scratch. This is going to be a new wallet, so all the assets will be reset to their initial state. If you want to take this path, please uninstall uTorrent, then get to %AppData%RoaminguTorrent and delete all files that are left. Then, do the same with the helper folder.
