Creative Cloud Desktop Says "Offline"

I recently installed Creative Cloud Desktop.  However when I open it, it says “Offline”.  I obviously do have Internet.  I have tried some suggested solutions, like setting my date and time to automatic.  I’ve checked my firewall but no listing for Adobe.  I have uninstalled and reinstalled Creative Cloud Desktop.  Nothing works.

But I should mention that when I installed the Creative Cloud Desktop and opened it, a dialogue box came up saying, “do you want to save or find the file ieframe.dll?”

Thanks for your help with this issue.
