Get a hold of Amazon. Tell them your computer crashed and it would be nice if they gave you a new download link for the book. You saved the receipt, right?
and life goes on...
I've purchased an audible book from amazon.com and downloaded it through web on 2002. My PC has crashed two times after then, but my documents have been saved. However, during that period the programs on my PC has been renewed. (Now i have Windows XP) Now, I needed the said audio book and downloaded MS Reader in order to listen to it. Unfortunately, when i click on my book, it gives an error ''the audible book you are trying to listen was activated for another user''. How can i solve this problem? How can i prove that i'm the same user? I'll be appreciated if you can guide me.
