Ok
So here is what I did and it worked.
When you are at the chrome:plugins you can see the location for the pep dll file.
Well, first in chrome:plugins disable the pep dll, then go to the folder containing the file and go up one level to delete the entire folder named PepperFlash. Delete it and restart your PC.
It worked perfect for me.
