Agreed, if you can't get a professional fit, try raising your seat. Pain on the inside of the knee generally means seat to close to pedals, outside means seat too far away.
Just a warning, less is more. 2 cm is less than 1 inch and is as far as you'd want to go with each move - ~1/4" moves are not a bad idea, greater than an inch are a bad idea. You can always raise a little more the next ride if a little helps in the first place.
Also, I'm a fan of stretching. My problems are outside of the knee, so my stretches are for that, but there must be some good stretches for the knee in general.
