Trouble with Comments

I don't know why, but blogger is not letting me comment as myself. Whenever I view my blog, it apparently signs me out, and when I try to sign back in to comment, it tries to post it as anonymous. So I haven't been responding to anyone's comments because I don't want to post anonymously. Anyone else who uses blogger have this problem/know how to fix it? It's minor, I know, but frustrating nonetheless.
