In AC7.0.7, I get the following error after filling out the form and clicking finish. Has anybody else encountered this.

WebException: The remote server returned an error: (500) Internal Server Error.]

SR 1 for 7.0.7 just came out and it does have some Fedex fixes

I found that there are fixes in Service Pack 1 that are supposed to fix this issue. I will be applying the service pack this weekend.

There are now two versions of the FedEx integration. The original version continues to work for existing customers who are already signed up. This integration will continue to return rates until May 31, 2012. The updated integration is needed for any new merchants. It is the replacement integration as FedEx is phasing out the old technology.

I'm still using AC 7.0.3 and only recently had a need/desire to register our store with a Fed-Ex account.

When I attempt to complete the Fed-Ex Registration within AC, we get the following error:

Exception of type 'System.Web.HttpUnhandledException' was thrown.; The remote server returned an error: (500) Internal Server Error.

Is the error likely due to the FedEx changes or should I still be able to register from 7.0.3?

Will I require the new FedEx integration files to make this work within 7.0.3?

Thanks!
