ebook freezes often

I just got digital access to an ebook through campusebookstore and it freezes often. In the 1st hour of use, it froze at least 5 times. Campusebookstore says it is an Adobe issue, but provided me with the following steps to take:

1. Delete the eBook from Adobe Digital Editions (ADE) and close the app.
2. Search your computer for all eBooks and delete each copy you find.
   
   eBooks are usually found in
   [My] Documents > [My] Digital Editions.
3. Delete the contents of the
   tasks
   and
   failed
   folders in
   [My] Documents > [My] Digital Editions > restore.
4. Delete temporary internet files. This step is extremely important.
5. Close and reopen your web browser.
6. Try downloading the eBook again

I also uninstalled and reinstalled Adobe digital editions. Once done, I tried using the ebook again and within 5 minutes it had frozen again. I am using a windows laptop purchased last year. I have also looked for a means to contact adobe customer care, but I keep being routed to a page that does not seem to have any email address or phone number on it. Can someone give me that information, and/or tell me what I should do next?
