Adobe Flash Installation Question? What's Wrong? This should be easy but....?

Okay, to start with, I am basically a computer illiterate, but here goes. I got a message to update my Flash player and I did. Now I'm getting all these mean messages telling me I don't have the right version, or that it isn't installed. I have Version 10. Should I uninstall it and start over, or what? I know this sounds stupid, but I just don't want to mess anything up.
