It is interesting who wrote "if you insert the numbers jetmouse keygen 1.5(don't forget to click "enable additional fields"), you'll get your 25 char key" in some post above

Only about 16 keys is available to store. You can see stored subscription title and so you can recognize the FID, PID and RgnID for it. And then as you wrote above: VenID= use "1" for insert and 0 for remove the provider. It works for me.
But you can reread thread and probably here was info about reset of GTM...
