I need to conciliate two e-mail accounts to correct the problem E_LIC_ALREADY_FULFILLED_BY_ANOTHER USER

No, I bought it from a local bookstore. The problem is that I forgot my user, so I typed use it without ID. while I created a new account. That was my biggest mistake because, first I was able to read the book at least in my computer, but not to copy into my Papyre. Now, I am not able to open in my computer neither in my Papyre. I requested to change my password of my first authorization (traductora@traduccionesdelvalle.com), but I cannot open my book. I read that I can reconciliate both emails: asdv33@ufm.edu and traductora@traduccionesdelvalle.com, but I am not sure. I am really sad that I can not buy any more ebooks because I won't be able to read them. Please help me.
