Your ratio is definitely too high, but the knee pain isn't necessarily something to worry about. If it's in the same place on each knee, then it may just be your legs adjusting to a new type of excercise (fixed is subtly different to bikes with a freewheel).
I had minor complaints from my knees at first, even with a low ratio. It went after a short while. but then again I am lucky enough to be in the limber years of my youth.
Also, another example - I recently started skidding with my weak foot forward, and that gave me knee pain in my left (weak) foot for a week or two, while it adjusted to the new strains that skidding puts on my muscles.
