Me neither. I'm a Pro user. The only download I can find is the free one and I'm concerned that I'll undo the Pro features if I upgrade with the free one.
As far a manual module updates go in Joomla, you might have the same issue as me. For security reasons, we disabled the server's ability to execute downloads. To do updates, I usually ftp the installer to the server, extract to a new directory (I call mine updates...). Then, you can run the module update by choosing install/uninstall from the Extensions menu option in Joomla, then choose the folder location of the extracted installation files.
