Simple two thoughts on this response, and I do mean them with respect.
My email provider is Yahoo, have used it for almost two decades happily, and always get important emails, not to mention I monitor my spam folder regularly. Plus, on top of that, you apparently did not even receive my "reset request" in the first place via the support page that I was linked to while logged into X-Aviation.com that I filled out and submitted:

My email is fine for purchases, receipts of purchases from your site, and I get all your emails, even the ones advertising SMPv4 coming soon, now released etc, and then when I need support, it's my email provider at fault and couldn't possibly be your site that might have a problem?
I really like your site and products, but I went through the proper channels and they did not work. You yourself can see I'm not a pirate based on my purchases, so obviously there is a problem at some point in the chain. I know others on avsim (and even support you over there) that have similar complaints (no, not that obsessive guy lol). All I'm saying is it would probably be worth your time to figure out why when we click "reset request" and then get linked to the form above, you don't get our tickets and we never get a reply.
