I keep getting a message when I log in that my username or password is incorrect and that I might need to contact my salesforce administrator and I do not know who that is. I am also confused because I just made this account and I know the information I put in is correct.

Make sure you go to go to: https://login.salesforce.com/ first and then try to log in.
If that doesn't work, try it in a different browser.
If that doesn't work try the Forgot You Password option.
Let me know, ok?
