Hi. Frustrating as it is, Your computer is programmed to make sure it is a human, (you) at the keyboard and not another computer. It cuts down on "spam" big time! As Momis4 said it is a safety precaution. fredg2013 is right too. You must pay attention to the cap and nocap letters. Sometimes they throw in number too. If there is a big space between them, use a space. If the are side by side, treat it as one big word. Your font probably won't be the same & sometimes they are had to read. If you've tried a bunch of times & it still doesn't work, but worry, it has happened to most of us! Let it rest and go to a different screen. Play solitaire or something for about 1/2 hour, then come back to it. One last trick, don't hit "enter"! Use your keypad or your mouse to move to the next line. Good Luck! You'll get it !!.
