It takes time and dedicated effort (fairly strenuous lifting according to a programme) to build muscle - I have read that men can gain 1.5lb a month (working hard at it) and women can expect to gain quite a bit less, max 1lb a month, 1/2 lb is more realistic.
This may sound strange to you, but you may not be getting enough calories. I was having trouble losing a few months ago and then I took a look at what kind of exercise I was doing and what I was eating. It wasn't enough food to properly maintain what my body needed. So, I upped it a little and also made sure to be getting lots of protein ( I strength train with weights - heavy stuff not light - in addition to my other work-outs), 4 to 5 servings of veggies or fruit per day, grains, low fat or fat free milk, and made sure I was taking my vitamins (just a one-a-day). The weight started coming off the week after I made the adjustment. Only a pound to a pound and a half per week but that's because I am gainning muscle while losing weight. Whatever you do for a work-out just compare it to your calorie intake as well. You may even want to talk to a nutricianist about it too. Good luck to you.
