I accidantly deleted my mails also with the link to the drm free version oh well then i have to wait till it can be dl from steam.

If you ordered from GOG, you have it in your "My Account".
If you ordered from AH directly, you should contact them, their customer support will likely re-send it to you after verifying credentials.
You could also always try to go the web version of your e-mail account and look for the e-mail there, chances are it's still there (if you're using IMAP or POP3 to download mails to your computer).

Thanks m8 for the reply I went to my web mail and it was there.
