I added these two lines to my code where you said, and everything seems to be
working for me now.
StandardDecryptionMaterial dm = new StandardDecryptionMaterial("");
doc.openProtection(dm);
Thank you so much for the help!
Thank you

You should call openProtection() here.
I'm surprised that this works in java, although I didn't test it.
Could you upload the original, the result good and bad files?
We don't do support for the .net versions (yours is an old one anyway), but
