Timeslips won't open

Help!!! This has never happened to me. I am working on a laptop with a single installation of Timeslips v. 2014 on a Windows 8 laptop. I had the computer on earlier today, then shut it down (not even in Timeslips) and when I turned it on and tried to go to Timeslips, I get this error:

The installation file Timeslip.CFG needs to be located before continuing. What the heck happened?

What Timeslip.CFG file am I suppose to choose to locate this, this is crazy!

Thanks for your help as always!
