Roon program shuts down 15 seconds after opening - Windows 7

Just installed Roon 5 days ago. All of a sudden today, it won’t stay open. I have Windows 7 professional. It opens and then shuts down saying there is a problem with the program. Up to now it was working very well. Please help!

I just sent you a PM @William_Rowe – take a look and we’ll figure out what’s going on here.

Thanks!
