Extract From PDF - End Of File error

I am getting this error when trying to extract from some downloaded pdfs:

Error from the Extract from PDF action. An error occurred reading the PDF document from the variable. The variable may not contain a valid PDF document: Error: End-of-File, expected line

The weird thing is that if I just keep running the robot, eventually it will work. Has anybody run in to this issue before?

Hi, I got another error which is "Access denied" when I tried to save the pdf file into a directory. Can someone let me know how to solve this issue as well? Thanks

Hi. I am facing a strange issue. After my pdf is downloaded in my directory, if I go to open it , I am getting "opening of pdf file failed in kapow" error. Can any one please help ?
