Missing HP, target, casting bars

[nythil]

After a server restart toady, my HP, target (those arched vertical bars in the center of the screen) and casting bars have all disappeared. I tried using nUI help but nothing seemed to reset them. I have also re-downloaded and reinstalled nUI but the bars will not return. I am far from a techie so any help you can give, no matter how basic would be appreciated. Thanks in advance.
