I installed the upgrade today, and it didn't go altogether smoothly. As I indicated in the subject line, my views history count or whatever it's called was reset.
I tried to automatically upgrade the plugin. WP downloaded the upgrade, but it threw an error installing it because (I think?) you've now got the widget incorporated as part of the main plugin file, instead of showing in my admin screen as a separate plugin? I thought no big deal, and just upgraded it the old fashioned way - downloaded the new version, installed it via FTP overwriting the deactivated old version.
Went into the admin plugins page and activated it, went to the RP settings page, everything looked OK. It said my oldest count was from back in December, when I originally installed the plugin. So I didn't do anything.
A few hours later, I come back and the widget output is all weird. Completely different posts than before, and one of them listed twice in a row (wtf?). I go back in and look at the settings page, and it says "Your oldest count is from 2010-03-21." What gives?
