I had this working fine on 1.3.9h apart from the telephone number for the delivery address which was causing the change of address to fail.

I did a file compare and up loaded the new version which was in the down load section as there seemed to be some changes. Now I cannot get the check out pages to load and the other module I have installed (AIS - Ajax Attribute Images Swapper) has also stopped working.

I can only assume this is related to a conflict with the jquery, but I cannot get the fist page of check out to load at all. Any ideas where I start to resolve.
