Apple Logic Pro /LogicExpress Discussion

Anyone here use Melodyne? I'm having to use it extensively but having
some problems. What it can do is amazing! but it's not without it's
uh,..shortcomings.

Just in case someone know this, here's the email i sent to their tech
support. Thanks all, in advance. 

Here's a repeated problem  i'm having  with Melodyne that i'd like to
overcome.
 
I'll start with a new Logic song, transfer the vocal track via the
bridge into a new Melodyne arrangement and then save. i'll edit, and
save again. what i want to do then, and can't, is close the current
logic song, open a new one, with a different tempo, and play. (both
the LSo and Mel Arr.)
but Melodyne will not play with the new Logic Song. It's seems to only
play with the Logic song that originally created it.

Here are the steps i take once in the new song.
1. First i close out all the files and reopen, Logic first.
1. Create an instance of the bridge in an empty track.
2. from the bridge window, select the Melodyne Arr. file to be played
3. select the right track in the 'Connect To' pull down menu
4. click the playback button.

What am i leaving out, or doing wrong?
