Hi there, only the standard shipping module is active. I may now have found the cause of the problem though - in the zones I had entered Britain as UK and I am told that it should in fact be GB which I have now altered. However this doe not explain why the problem has only just begun, particularly as I have had UK inserted for many many months.. Anyway, I will hope that this alteration has now cured my problem but thank you again to everyone who answered my plea. Mery Christmas to you all..
