XML Notepad 2007 - basically unusable - possibly "Global Element / global attribute" "has been declared" error?

Apr 24 at 7:09 PM
Two days ago my XML notepad 2007 started to act sluggish. Checked as much as I could before deciding to uninstall it. Reinstalled and still having the same issue.

opening files, making changes to the tree (insert, edits, etc...) are taking an excessive amount of time. The software continues to go unresponsive when changes are attempted.

I found that the "Error List" is MASSIVE. Tons of errors indicating "the global element "" has already been declared". Or the Global attribute has already been declared.

Does anyone know if this is something that I may have triggered?

I use this software a lot to edit configuration files. In it's current condition the software is unusable.

ANY HELP would be greatly appreciated!

Thanks!
