Root Need help please installing ROM

[maskins]

I was messing around with titanium backup earlier like an idiot and now my Android Market will not work. So I read somewhere that if i did a factory reset that I could get it back right... WRONG.. it is still gone, as well as every other app i had downloaded. What can I do?
?
