DRM and Adobe ID problem

Hallo! I downloaded a drm protectet book with adobe digitals. Before downloading i didnt log in with my adobe ID. (I wonder how this is possible) I tried to link my adobe ID to my ipad (Bluefire Reader) but it didnt work. Then i uninstalled adobe digitals and reinstalled it and now it wont let me open the book because i didnt download the book with my adobe id. (I wasnt logged in while downloading). what am i supposed to do? How can i make it work again? now i cant even print the book...
