az, I'm not positive. And since I donated/registered, I don't have the restricted version to test for you.
I either:
a) made sure each of the individual sub-items was disabled in the Left Hand Post-Processing Actions panel (and hence not displayed in the actual Export Dialog), or
b) I actually removed it using the Plug-in Manager. It's relatively easy to install and uninstall export plugins using the manager. The gotcha here is, you can't have the plug-in components existing in the 'Modules' subfolder. Due to backwards compatibility with Lr 1.x, any plug-ins in that folder will be 'auto-installed', and can't be managed with the pug-in manager.
That's a bunch of goobledy-gook, if I didn't make it clear enough, ask some more....
