I cannot load a PDF file from my exterior CD/DVD drive. When I insert the CD, the file appears on the screen . I click it and i t runs for about 1 minute, then it stops. It says on screen....COULD NOT OPEN PDF, Something is keeping the PDF from opening, The size of the PDF file is 1117 pages or 130 MB. Do I need more storage to read this file? I have 128 GB solid state drive and 8 GB of memory. Do I need more storage to view this file and how would I do this.... or what can I do to rectify the s problem? Thank you for your help.
