Toad for Oracle (Not Responding)

I have Toad for Oracle 13.3 (64-bit).

Up until yesterday, it's been working fine. Now when I launch the application, it goes into (Not Responding) mode. I've tried rebooting twice, but there is no difference.

The only thing I can do is End Task from Task Manager.

Any suggestions on how I can get this working again?

Thank you.

Just to follow-up on this, I ended up uninstalling and reinstalling.

It is working again. Still not sure what caused this in the first place, but I am back in business.

I'm glad that solved it. I'm not sure what would have caused it either.
