I have this same issue. I would think there would be an ini file or a checkbox for disabling this warning screen as many people like myself must have installed the plugin all at once with the other plugins to make sure the installs worked (especially with the goofy registration -2 -3 -4 -5, etc.) without having cameras purchased yet but who also want to skip the warning box everytime AHP is launched. Perhaps this needs to be a future feature to the software to be able to turn off the warning. I may add a camera someday, but for now the warning is just annoying and I won't be uninstalling AHP to get rid of it. Oh well, at least all the plugins light up neatly upon program startup. I didn't like them greyed out like that, just taunting me, teasing me. Now the plugin icons are in full color, just the way I like them.
Damn warning screen. Kiss my ***.
