BlogEngine Paypal

I'm trying to get BlogEngine working with ExpressCheckout. I've tested the API credntials with the same user controls as I'm using with BlogEngine and they work. In BlogEngine, however, I get "Sorry, an error occurred after you clicked the last link". I'm using the same .ascx user control and the same API settings and credentials.

In BlogEngine, if I use Firefox I can get to the PayPal login screen without problems, but with IE or Chrome (IE7 and IE8) on low privacy and security settings, I get the error.

I've tried sandbox and live credentials but I really don't know what else to try. I'm using the MarkExpressCheckout method on PayPal's NVP C# samples and have never had problems before. Could some part of BlogEngine be interfering somehow? I'm running ASP.NET 4.

If it helps, my site/checkout is 开发者_StackOverflow社区at http://chickenping.com (http://chickenping.com/category.aspx to add prroducts to the cart).

This was caused by passing the country as United Kingdom rather than GB (which works)
