Did you ever get the automated reply noting yout ticket number and the details to access it on the support site? If not, check your spam/bulk filtering. Some webmail hosts such as hotmail have also been known to blackhole support mails silently in the past as well, so if you're using something like that, try it from your ISP mail account or another that isn't filtered.
Failing all else, you can submit a ticket directly through
this page. Just click next, then fill out the form and submit it (no need to log in or register there).
