Just a suggestion … if you’re still struggling, you might find a programme called ‘Tweaking, All-In-One’ helpful.. Even the free version has gotten me out of some problems I might otherwise had a lot of trouble sorting out.

copy and paste given code ..does nothing will not register at all hmmm got another code we can use plzzzzzzz.

Thank-you Ashraf and Driver Magician. Have found this a useful program. No trouble with registration; I had an older version from GOTD and this version accepted the old registration.

Its OK.
