i actually enjoyed the lighter notes there.
did you try the suggestion here -

how does it sound using the vent setup/test button function
you can also try this, though i don't like doing this myself:
Starting From Scratch
Write down your Username and Server information
exit vent
goto START/RUN and enter: %appdata%\ventrilo
right-click on ventrilo2.ini and select “Rename”
give the file a different name
or
delete the Ventrilo folder
restart vent
re-enter your username and server information
