I have this and it runs ok, but i have a 300 page pdf file of 12 mb, and it wont load.
So i thought it was because it was a big file, so i tried a different pdf which was 2.5mb, which worked.
Then i changed the original file to 50 pages or 1.7mb, and it wont load.
Ive changed file name incase it was too long, but it still wont load.
It also isnt protected.
