I have solved the problem. I pretended to log in to another site, and it worked quite well.
The problem was I had downloaded Last Pass (which I have on desktop) and the particular Last Pass page I was trying to log into, would not accept the _ & @ - I got out of Last Pass altogether, rebooted, and found the application again - this time I opened it up to log in (different page) and it worked fine.
Sorry to cause you all problems, but thanks for helping anyway.
