if you're on FB, I'd suggest going to the CGL FB page, and using their "Send Message" thing. I had a problem with a SR novella from April 22 not giving me the download link. I tried their "Contact Us" form on the store site multiple times, as well as their Customer Support email, and never got a reply. Even posted here about it, and nothing. :-\
Took a little back and forth with the PM thing on their FB page, and one of their Volunteers was finally able to help me get the novella I'd paid for. :thumbsup:
