When combining files, conversion keeps failing with a red notice that the document is password protected. I was combining all pdf files and had just been successful with some of the same content under a different file name. What is wrong and how do I correct it?

Hey SUSANO,

I am sorry but you cannot combine files if they are password protected.

You can check the same under 'File > Properties> Security

But they are MY files!! Lmao!  It's my certificates and I need them all in one file to send it to a Board of Nursing.  Otherwise, I would not have paid for a year of this service!
