Big change after v2.4 but still worth using.

I originally decided to use this plugin as it added almost out-of-the-box support for Paypal in conjunction with Contact Form 7. A site that I was working with got in contact with me to say that the plugin had stopped working. After some investigation, I found that the plugin had a major jump in how it connected with Paypal ( v2.4 -> 2.5 ) and that it stopped the plugin working and instead displayed the shortcode. I read through the instructions to setup the updated plugin and found it pretty complex in comparison of the 2.4 and previous setup. Having said that, I guess it is probably a warranted update and once I get it working on my dev site, i will be able to upgrade the various websites that I have still on 2.4 as it is a great plugin. Props to the development team. I hope you see this as not a gripe but as reflective feedback.
