This wallet never opens for me on Windows 8.1, it just crashes while loading each time, no idea what to do :/
Sometimes when you close out the Windows wallet, it doesn't completely close out so that the next time
you go to open it, you get an error. Go to your task manager (CTRL-ALT-DELETE) and look under Background
Processes. You'll see the Singularity wallet there. Highlight it and click the END button then close out the
task manager. Now you should be able to run the wallet no problem.
