EMERGENCY!!!! ADOBE PDF FILE FORMAT IS HAVING DIFFICULTIES. BAD PARAMETER!

I need to send this to my client in a few hours and I just completed it. I have been exporting the files as pdfs to go into a template for a large event booth.

can you see this? 

Bad Parameter  https://drive.google.com/file/d/1nJ89fRrKW2O1szwcSyUXZZkGMceuh8Tv/view?usp=sharing

just this morning when I was doing the final touches of over 80 hours of work, I CAN NO LONGER SAVE. I CAN NO LONGER EXPORT AS A PDF. I CAN'T SAVE A COPY. I CAN'T EXPORT ANY OTHER FORMATS! 

HELP ME SOMEONE I'M BEGGING YOU!!!

I was initially getting an esoteric message about my transparency blend space not matching my destination when I put it into the template. They are both on CMYK and the huge list of color choices for me to choose from make no sence. I have never had this problem in my 15 years of working in Illustrator. 

Does someone know a work around?

Of course Adobe is not available on Sundays. I'm so screwed. Anybody out there can help me???

Thank you,

Heather
