Ubuntu – Blank Terminal

command line

I can open terminal with CtrlAltT, but, it's completely blank and no way to input anything?
I tried typing just in case there was something hidden but it's as though the font is black on black.
I've tried changing font colours but it didn't do anything
I have Ubuntu 12.04 LTS installed
How do I get to see what I'm doing (or what did I do to screw up?)
Thanks in advance

for me the problem was a previous command that had crashed. Ctrl + C broke out of it for me. Perhaps something everybody knows, but not me until now!
