My PC just finished doing an update for Windows 10... and now the STO launcher won't work. I'm going in through ARC, I click on "Play", and nothing appears to happen. Looking at the task manager while I do this - the launcher starts up, then the Windows Problem Reporting Service starts up, and then both of them go away. So I'm inclined to think something in the launcher must not be playing nicely with the Win10 update.
Any thoughts on whether today's patches might help with this? Or whether there's any other possible workaround?
