Google Maps plugin settings appear briefly, then disappear...

Hello, I have now installed the google maps plugin on two different test sites and am not sure what I'm doing wrong. No matter what I try, I cannot access the settings for the plugin. I can see the settings page for them - but when I click on google maps, I see the settings appear for a second and then disappear. I have deactivated all the other plugins as well to see if something was conflicting and same result. Any ideas what the issue might be?
