ran across this message while installing X3e...

I have an image to post, but cannot find the way to attach it...  "attach images" icon doesn't allow me to browse to the image...?
The message says:
Melodyne single track.
*Modify
*Repair 
*Remove
What does it mean, and what should i do?  Melodyne was working fine last time i checked.  TIA
 

Thanks, scook.
If i choose cancel, will it still install Xe OK. 
BTW - It only says it is "finishing" the 3e install, not that it was installed.
The green bar is all the way across, but the install panel is still open. (so two panels are open ATM).

Thanks, scook.
