Thanks for your help! It's weird that the VIX plugin was the issue because I've had that on there since before I created any workflows. Perhaps I had a server restart or something that enabled it, though.
Thanks again!
***For those reading this that don't know how to uninstall the plugin...go into the vCO configuration, under the plugins tab and uncheck that. You'll probably need to restart the service or the server under the Startup tab as well. I had to do it a couple different times before it was actually gone out of my inventory on the vCO client.
