[PREMIUM] PornoKox v1.0 - XVIDEOS Plugin Extractor with Custom Video Player

Can you use the watermark feature on the Free version? I did download this plugin and it's not that bad but i wasn't sure if it made my site go quite slow so i've deactivated it but not deleted it. I was kinda hoping someone else who may have downloaded this to try has any thoughts on it. I mean if your just starting out and want some quick vids uploaded to your tube site than this is awesome but like i say it did seem to slow my site down but it could have been bad timing so i'm still waiting patiently for other uses thoughts on this product and has anyone bought premium?
