Fails to start Stykz after power interruptions

Hello Guys,
These error happens when I’m at a middle of my editing project when power interruptions comes then switch on again the desktop and fails to start Stykz.
How can I resolve this error?
How can I retrieve the unsaved files? If there’s an option can you please guide me?
I would really appreciate all inputs.
Thanks.

The program can’t start because QTCF.dll is missing from your computer. Try reinstalling the program to fix this problem.
OK
