I was looking into purchasing the premium version of Supra CSV, but the link to your purchase page, which was in the WordPress plugin, as http://www.supraliminalsolutions.com/blog/downloads/supra-csv-premium/ and didn't work.
I also finally found a link to purchase it at http://www.supraliminalsolutions.com/blog/listings/supra-csv/ .. but it was so confusing (asking for a PIN) that I didn't know what to do.
So I entered a 4 numbered (pin) but then it gave me an error message:
Fatal error: Call to a member function getId() on a non-object in /home1/suprali1/public_html/versionSubscription/apps/frontend/modules/purchase/actions/actions.class.php on line 66
So .. I'm not feeling very confident in purchasing your premium plugin, if your website functions like this.
Please contact me back and let me know what's up .. what the premium version costs, etc.?
