Over the past month (since Craftsy redesigned their site) I have heard from several people who had issues downloading patterns that they purchased from Craftsy. They are aware that this is an issue and haven't been able to resolve it yet. Once their website lets me view the pattern order history (that portion of their website is currently not functioning), I will be emailing each person that purchased my pattern from Craftsy over the past few weeks with a link to download the pattern PDFs.
In the meantime, if you are interested in purchasing one of my patterns, they are all available on Etsy and appear to be downloading fine. If you have any issues, please contact me at email@example.com and I will help resolve them as quickly as possible.
