Ok I think I have this in the correct spot! I HOPE !

I have previously downloaded some designs from http://inthehoopdesign.com but now when I place something in my cart and press the download file button it tells me to 'invalid email addrtess : go to homepage' but then just takes me straight back to the designs. Don't know if that makes sense but I hope it does. I have stitched up the moon tic tac toe and showed it in projects here but I have also not being able to say thanks to Sarah to owns that site.
Thanks in advance for any help anyone can offer me !!!
:D
