OK...I think I have messed up the extension library install.  Step 1 was great and I was able to confirm that the plugins were installed.  Step 2 however messed everything up.  I think instead of unzipping the files into the Features folder I copied them in.  Then I started getting the "EUM UI Job has encountered a problem."  Along with other errors that I can't recall right now.  Frusterated at this point I just deleted the files that I had copied in (I know, I know, bad user).  Thinking I could just perform the install again and it would overwrite everything that I had done I tried to install again and now I get this message and it goes through the install steps but in the ends it errors.

I don't have the option in Application Manager to uninstall anything.  They don't even show up there anymore and they are gone from my Plug Ins list. 

How can I undo everything and start over?  Will a reload of my Designer get me back to before I messed everything up?

I appreciate any help!
