Not a problem. I am completely devoted to this modification coming across as A+
Only other thing I can think of is to ensure you have enabled Email Integration and have fully filled out the email address user's should reply to as a full email address in the Forum Manager.
Anyway, if you'd like, pm me with an admin login. I'll need access to the vbulletin options (to verify the settings for EI), forum manager (to verify the forum settings), plugin manager (to make sure there isn't any problems with other mods messin each other up) and what forum you have enabled
With the problem your describing that should let me resolve this problem and confirm if this is a bug or a issue between two mods.
