Cannot share my desktop or an application

I currently am unable to share either my desktop or a specific application in the Share Pod in several of my meetings. When I click the "Documents" drop down under "What do you want to share?" the only option I have is "Select from Content Library." Before, I had the option of (1) Desktop (2) Application (3) Content Library (?).

I am wondering if this is related to something else: at the same time I started experiencing the issue stated above, my Adobe Connect meeting started opening in a tab within Internet Explorer, instead of as a unique Adobe Connect application.

I have attached a screen shot showing what I get when I try to share my desktop/an application.

Thanks!
