Hi Stephanie,
Not sure if you sorted this out or not.
I had exactly the same problem you described and after going around in circles for a few hours finally tracked the problem down so will post the solution here in case it helps anyone else.
In my case it turned out to be suPHP doing its job.
The default permissions in the cforms II plugin folder were insufficient to keep it happy.
Counter-intuitively, relaxing the permissions makes things worse – they need to be tightened up.
Make sure all troublesome plugin files and directories are only writeable by the owner i.e strictly 644 and 755 respectively.
This fixed things up fine for me with WP 2.8.4 & cformsII 10.6
Best Regards,
Phil
