1Password 3 Uninstall

My fault, oh boy. A great suggestion from Stephen if only my iMac would have allowed my using the uninstaller provided by 1Password 4 to remove 1 Password 3. But because I hadn't acquired my upgrade from the Apple Store, I was not allowed to use the uninstaller, not authorized or something. Here's the stupid part. I used an uninstaller called Trash, which has been fine for all my other un-installations--if that's a word. But it was not the selective uninstaller that AgileBits provides. Where am I now? 1Password 4 is working but only because it is accessing items in my Mac Trash that I was not allowed to throw out because one of them was in use. So I know that everything I need to make 4 whole again is in the trash along with everything from 3 that I wanted to throw out. Would greatly appreciate any suggestions. Thank you.
