Usually having the seat too low is more likely to cause knee problems than having it too high. (Though too high can cause problems in some cases.) But being in too high a gear and pedaling too slow is more often the major problem. As a rule, even when cycling casually you should maintain a cadence of at least 60 RPM, and when touring somewhere in the 70-90 range. Adjust the gears, not your cadence, as the terrain gets easier and harder.
What you're probably suffering from is "patello-femeral pain", a condition where the area between the kneecap and the knee bone becomes inflammed, often at least in part because the muscles pulling on the kneecap are pulling off-center.
A visit to a sports rehabilitation therapist is probably in order, but there are a few simple exercises that usually help. The simplest of these is to lay on your back, keep the knee perfectly straight (odd as that may seem) and do leg lifts, lifting your foot 6-8 inches off the ground. Work up to about 100 of these a day, on each leg (even if both aren't bothering you).
There are other exercises, but they need to be taught by the sports rehab guy.
This isn't usually a serious problem, but tending to it right away can get you back in the saddle faster.
