Emporer scorpion doing all right?

I have an emperor scorpion that I bought from PJ's pet center in March. I have a few things to ask. This my my first true exotic pet, so I just need some back up. I have no idea if it is a male or female, but I belive it may be female. I got her in March, and she hasn't molted yet, and she is not very big, but she is a fair size. Shouldn't she of molted by now? Second, she rarly comes out of her hut, even at night. and she has a habit of tryying to crawl out of her tank, and thats prettyt much all she does. TYry to crawl out, drink, or sleep in her hut. Is their anything wrong with her?
