The ST.Protect.Native log contains the following error:
Unable to load the custom XML file [C:\ProgramData\Shavlik Technologies\NetChk\pathtoxmlfile]
Protect is attempting and failing to import an invalid custom patch XML created by the user.
Navigate to directory containing custom patch XML.

Identify the custom patch file by its .XML extension, right click the file, choose rename, add .OLD at the end.
This will effectively remove the file from being processed by Protect, and allow verifying that the abscense of that file fixes the problem.
