did you remove the correct addin? if it is disabled, find and delete
extend.dat. Or better yet, uninstall the winfax outlook integration since
it will not work with outlook 2007.

I uninstalled all of Winfax program plus the Outlook integration, but
that alone did not fix the problem. Deleting the extend.dat fixed it.
Thanks so much for your help! :)
