Wordpress MU Affiliate - premium download has lite version.

OK, I learned from a previous post that I can't auto update the Membership plugin as it "upgrades" to the "lite" version.

But in this case I've tried downloading from the premium downloads twice, and the zip file has the lite version. The file structure is :

wordpress-mu-affiliate-1.2.zip/affiliate/affiliatelite.php

Is this right? Or is there a non-lite version available?

Thanks,

James
