I'm having trouble with the new shipping options. I get a OS error message, or if I get all the way to the listing page on ebay, I get a shipping error message. After I input the demanded information and click to continue, the next page is an error page. What if anything, am I doing wrong?

Hi, I got the same message a time or two. When I double-checked that I had selected an actual shipping service (such as Standard Flat Rate, instead of leaving the default) then the error went away. Hope that makes sense :)
