Can you help with this PDF issue?

Continuation of this question.

I got a call to interview for a position. I had a staff ap filled out but I need to edit it, and it’s just giving me fits. I’m honestly about to cry. I’ve been messing with it for HOURS! I don’t know why it won’t let me edit.

I’ve tried using the PDF editors suggested in the first question, but they just keep going in a loop. It’s supposed to be a free editor but every time I try to do something I get a pop up demanding that I start their free trial. Even if I say “OK” to the free trial it still pops up. It just goes around and around.

I found other editors, and was able to edit and save. But when I try to reopen it, it won’t open. Or it goes directly to the PDF editor website.

I’ve tried opening it with different extensions.
