EDIT### Updating to 40.2 got me going again.
I am running Windows 10, have used this PC for years. Recently Logos stopped opening for me. I get the blue splash screen that shows the version number, then it just goes away and nothing happens. I am running 40.1.
I tried uninstalling Logos and deleting the entire appdata folder but upon re-install it is doing the same thing. I am at a loss and at this time completely locked out of software I paid good money for. Anyone seen this before?
