iIf I understand what you are asking, try this:
Select the "Window" menu, and look for a checkmark next to "Metadata Panel". If there isn't one, click on it, and the panel should appear. If there is one, then I don't know what the problem might be.
I got understood what you are saying i also had faced it ..I also uninstalled it and after this I lost.
I tell you what you have to

do !! So first go to the ''Windows menu'' and click to the Metadata Panel..If it shows then here you can easily get the panel otherwise, there is another problem and you have to completely reinstall it "
Thanks you
