Wow...

What version of 4.22 are you using? The latest is v4.22c.

What version of IT are you using? The latest v1.30a.

Are you programming the VT key using IT or through the keyset. I'm guessing you are using IT to program. If so, try using the keyset to reprogram her phone. IT still has a few bugs and it wouldn't surprise me if that's what is causing your problems.
