It used to work perfectly. I just checked it again, removed plugins and added them back, and no luck. What happened?

what is the url to download the plugin?
Have you contacted teh plugin author?
have you changed anything - added a new plugin, do an upgrade?

Got it. Went to the plug in site and checked the boxes it said to. What a novel idea! It works now. I think they changed the requirements for the plug in without notifying users. Thanks.
