Hi Sylvian,
I'm not sure what you meant by support@digi.com, but that's a dead e-mail address if you actually sent an e-mail there. If you just meant it as a reference rather than an actual e-mail address, disregard this post.
If you need to open a support case online, go to the following link:

Best Regards,
Michael
