If you are using Hotmail or Yahoo email accounts, there is a very strong possibility NOT to receive e-mails from Us. Both the above use to "Mark" emails from PTC sites as "Trash" or "Spam" and place them in your Trash Folder. They even deny to deliver you the email and return it to the PTC sites' admins as Failed and Undelivered.
WE STRONGLY Recommand to use Google mail (Gmail). If all though you asked for help or password reset and you didnt get any email, Try to send us a support ticket. KEEP the ticket's Number so you can track it without emails. If still you cannot reach us there is another way. LOGIN to our FORUM and SEND a Private message to the admin.
