I bought an E-textbook through Adobe digital editions. I recently got a new computer and transferred everything over to the new one, including adobe digital editions. The book is still here, however it won't let me open the book because it shows a message saying "activation server error". I have tried erasing the authorization on the old computer and when that didn't work I tried erasing the authorization on this computer and re-authorizing but it will not let me. I also tried re downloading adobe digital editions and that didn't work either. I need to open and read this book for homework for my class, but it won't let me.
