I will reopen this thread to post some new information.
I waited to check my scores online until I recieved an e-mail notification that they were ready for viewing (about 15 days after I took the test). Thereupon I attemped to got the same "the information provided does not...blah blah blah" that other users have noted.
I sent an e-mail, as the ETS site instructed me to in case I could not view my scores, but to no avail.
I called ETS, and the problem was that long ago (4 years) I had taken the computer based GRE, and the account I created for this messed up the system. In general, creating multiple accounts seems to be one cause of this error. The ETS operator merged and reset my accounts, and the problem was solved.
In short, if this happens to you, call ETS and don't panic. They will most likely fix it.
