Nancy from Twisty's got in touch with me and let me know that my linkcodes were busted, was nice of her, but why they stopped working is another issue.
My old links looked like this:

New link looks like this:
http://secure.twistys.com/track/tcass:trial:twistys/
Maybe I missed an e-mail, or maybe this has to do with the sale to Manwin, I'm not sure really. Either way just a friendly reminder to check your linkcodes.
