[OPEN] Why can't I open this PDF file?

I am trying to load the attached PDF document into txTextControl. It gives no error when I loaded it but just shows 3 pages of blank content instead of the actual PDF document. You can recreate this using the demo application provided with your program.

I am using txTextControl v 17

Here is the file ( I could not upload it to this thread, must be too large)
