[Plugin: Universal Post Manager] Problem with Saving Manager

Dear Support Team:

I installed the universal post manager plugin. All I need is the print, pdf, and email button. First, I got the print and pdf to work. However, the email does not show up even though I turned it on. Anybody knows what to do?

Then I wanted to change the button for the print and pdf. I prefer the icon over the button. So I went to Settings to change the options. I got this to work for the print. But for the pdf (under Saving Manager), I was not able to change this. It did not let me update the new option. It appeared the update options button for the pdf was not functioning. Then when I went out and came back to the Saving Manager, the icon and button totally disappeared. Meaning, there is now a red x instead of the button and the icon. Thus, now I do not even have the button for the PDF anymore. Is there anybody that knows what to do?
