Duplicate id of packages "Templates"

I get the error below whenever I try to start Toad Data Modeler. I did a system-wide search for all *.txg files and couldn't find either "Templates 2.txg" or "Templates 3.txg". I did find "Templates.txg" and deleted that, but that made no difference.

Any ideas?

if I remember good templates.txg is packages which is copied from "Program Files\Quest Software\Toad Data Modeler X.X.\Packages\User" to "[Documents]\Toad Data Modeler\Standard Installation\Packages{DCB5CB9B-CF65-4350-86B5-285D246FC5AC}" folder.
So if you delete this file from documents folder it will be recreated. Please delete Templates 2.txg and Templates 3.txg.
