Problem Saving Settings with New Sociable Plugin Update

Hi, I installed the new Sociable plugin update (4.2.8) today. I updated the sociable classic settings on the sociable options page. Specifically, I changed the size of the icons, the icons, and the buttons that I want to appear on my site on the options page. I then saved these settings. When I go to my site, however, the default settings appear and when I return to the options page it has reverted to the default settings.

I have tried changing the settings a couple of times and have tried reinstalling the plugin. Any suggestions as to how to fix this problem would be greatly appreciated.

Thank you!
