I have a digital e book that i have been using for the past two weeks. This morning I had to restart my computer and I could not reopen the book. The error message i get is "Adobe digital edition 3 has stopped working". It has worked up to this point. I have a windows 8 computer and purchased and downloaded the book from a University bookstore for an online class. There was no problems using the book until this morning. I have emailed the bookstore for help, but thought I would see if anyone here could help me.
