Can't Keyframe

All Tutorials show that all I have to do is hit “I” and I can put in Key frames. But each time I try, it says Error “Keying set failed to insert Keyframe”

If you are trying to add a keyframe in the ipo window, and there is no keyframe already set, you get that error. To set a keyframe in the ipo window, I think you have to activate one of more channels, and then use ctrl I.

Well I started having alot errors and problems. Did full out uninstall and reinstall of program and issues I was having seemed to poofed.
