I tried to install the Pro version through Add New Plugin, and it wouldn’t install because it said the directory already existed (from having the free version installed). This support page says the free version needs to be installed before installing the Pro plugin, but that doesn’t seem to be the case since they’re in conflict. I’ve tried manual upload via FTP, and it seems all that did was overwrite the free plugin directory with the paid plugin directory, since I have none of the Pro features (or ability to add my license) from the admin. Please clarify what needs to be installed (free? paid? both?) and if both, how to accomplish this since they both have the same directory name.
