For gaining muscle you will need to eat at a calorie surplus, I have been around your weight/height and I needed about 1650 calories to maintain my weight WITHOUT exercise. Eating probably 100-200 calories OVER your maintenance would probably be a good idea.
I would also suggest not running every day, your body needs time to rest and if you are running for an hour a day that could possibly be 70km a week, which is a lot of pressure on your joints. Also, running practically wastes away the muscle.
Maybe running say every second day and on the days inbetween do resistance training or non-impact cardio such as bike riding, rowing, tennis, or fun stuff like rock climbing, swimming, etc. Gotta keep it fun!
I know what position you are in, I suffered anorexia for seven years from age 10, and at my lowest I was 5'7" and 100lbs, when I started to recover my body fat sky rocketed because I had such low levels of lean body mass and my metabolism had slowed to a crawl. I worked with a sports dietician and a personal trainer to get my body fat levels down (after I believed I had psychologically recovered), I went from 30% body fat to 22% body fat through eating around 1700 calories a day, and doing a lot of low impact cardio like swimming and walking, and building my muscle back up doing resistance training. I have begun running again, around 30km a week, but it's not terribly great for my body. I take Glutamine to help with muscle recovery, glucosamine for my joints, and I make sure I am getting sufficient vitamins and minerals so I stay healthy.
To answer your original question, it is harder for people at a lower weight to maintain muscle. I am not sure why, but people who are heavier do not really have to worry about losing muscle. a few guidelines to follow to prevent muscle loss
* Don't run every day, keep your runs every second day and only run one loooong run once per week.
* Don't to intense exercise in the morning on an empty stomach, this CAN cause your body to use muscle for fuel.
* Do intense exercise at night
* Don't keep your calories too low, if you do you will lose fat but also muscle, which will slow your metabolism.
* Keep your protein high and it is most important to do resistance training.
