Relink ACSM file to account possible?

Hi all,

some time ago I activated an ebook with my account via the acsm file. Then I deleted this account since I forgot that this book was linked to it. Now, I created a new account with the same mail address but cannot link the purchase to my account:

E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER.

Is there any way to link the purchase I made with my new account to get the ebook back?

Cheers,

Dom
