I am using a MacBook Pro and Adobe Acrobat Reader DC. I purchased an etextbook from Pearson that expires in 160 days. The instructions read,
NOTE ABOUT DESKTOP PRINTING: Your ebook permits only ONE desktop printing session. If you wish to print your entire digital publication, you must print the entire file all at once. Printing just a portion will count as your one and only session.
IMPORTANT FOR MAC USERS: The FileOpen plug-in is not currently compatible with Adobe Reader 11 for Mac. If you are using Mac OS X, please use Adobe Reader 10, available here:http://www.adobe.com/support/downloads/product.jsp?platform=macintosh&product=10
The weird thing is, I've been opening the etext in Adobe (with the plug-in downloaded as stated above) successfully for a week. I now get the error message "The server answer is an HTML error page." I haven't made any changes to Adobe or my laptop. I've contacted Pearson and they don't know what the problem is.
I also can't seem to download an older version of Adobe Acrobat Reader even when directed to that website, but I feel like that's irrelevant since I was viewing the etext on Adobe for a week even with Adobe Acrobat Reader DC.
What does this error message mean?
Please let us know the exact dot version of Reader DC and OS Installed on your system.
The pop up seems to be generated as a response to the plugin not being able to open the file.
