My .02:
I'm not sure I would classify the original post as "rediculously bad" in an era of over-zealous spam filters.
If you didn't receive a registration code by email, and then didn't receive a reply to a support query from the same email address, then very likely it's an email problem.
I understand it's frustrating, and THE SAME THING happened to me: I didn't receive a registration code... then emailed support about it... didn't get a reply... and then thought about it for a while. In my next support email, I gave an alternate email address under the assumption that my ISP was filtering my emails from Cake (as they do with Apple and MOTU). I then received my registration the following day, at the alternate email address.
It's annoying, but I don't see more than that... I've had much worse from other companies (Apple comes to mind...) that just don't care anything about you. I don't see that from Cakewalk... seriously.
The reality is that ISPs are filtering more and more of your email BEFORE it even gets to your inbox, and before it gets to your local machine and IT'S spam filter. It's recent technology, and it's got plenty of bugs to work out...
Moreover, ISPs upgrade the filtering software, trying to find the "best" one... you might get emails today, but not tomorrow.
Personally, I find email less reliable now than it was 3 or 4 years ago, but I get MUCH less junk mail than I once did.
A simple fix on Cakewalk's part that would help a lot would be to allow alternate email credentials during registration... two email addresses.
It wouldn't help everyone, but the percentage of users not receiving emails at either one would certainly decrease.
If you don't get emails from support, supply another email address... they're free...
From the many threads here and at a few other forum sites, this problem is increasing all around... MOTU and Apple both have it, and both have had it with my addresses. Occasionally, one rogue email will actually get through...
Take care,
