Intiface, blank screen after start up

I have an isuue with intiface central, when I start the app, I only get a blank window and I cant seem to figure it out. I tried older versions of app, same result.
I saw someone having same issue before, but problem is somewhere else in my case.

Try deleting the configuration directory. Assuming you’re on windows, it should be at c:\Users[your user name]\AppData\Roaming\com.nonpolynomial\intiface-central or something like that.

Thank you I will try that when I can.

Sorry for late response only now had chance to try it. Anyway it solved my problem, thanks.
