Field 'ID_LETTER' doesn't have a default value

[mnewnam]

I am using SMF 2.0.8.  I just installed Newsletter Pro and I am trying to create a new list.  When I try to add a new email address I get the following:

Field 'ID_LETTER' doesn't have a default value
File: C:\mysite\smf\Sources\NewsPro2.php
Line: 684

What do I need to do to fix this?

Thanks,
Mark
