First: Two hours a day of exercise is excessive for most people. You should be able to do more intense exercise for anywhere from 30-60 minutes and get good results.
Second: When you say "greatly lowered" ... what exactly do you mean? If you lower your calories too much, you could actually have the opposite result, because you're depriving your body of needed nutrition.
Third: Two weeks isn't really very long. Some people take longer than that for their bodies to readjust to a different "system". If you've made huge, drastic changes, you need to give your body time to acclimate. Many people don't see an immediate loss, but tend to lose in fits and starts, rather than gradually and consistently.
However, in general it's going to be hard for anyone to give you any advice until we know more ... so details please!
