As the real developer of PICKitPlus and the database that was plagiarized 
by PK- I am the right person to help.

When our database was copied the developer decided to change the order that 
the chip families are searched.  I wrote a detailed analysis for him and he 
ignored. So, using PK- can apply the incorrect voltage your PCB during 
startup.

Which chip or chips have this issue?  This will help me isolate the issue.
