pdf exports with errors, never done this before..

[herbiehysteria]

Hi guys, I'm trying to export two sides of an A4 flyer artwork and everytime i try to export as a pdf, i get the pdf created but with elements missing and the error from Adobe Reader says 'This pdf has errors... please contact the pdf author' etc. I've tweaked and changed so many settings but this has got me stumped. I use XX5 and have attached both .xar documents. I have converted all the text to editable shapes.

I would appreciate if somebody could export these as pdfs (PDF/X-1a: 2001 (ISO 15930-1) with 100% jpeg quality.

Page is already set with the 3mm bleed. I use XEP5.

Thanks, would be very grateful as I have a print deadline I am already way past.
