After updating Adobe Reader to 9.3.3 I run into the Invalid Color Space error when trying to open a PDF file created with CorelDraw 12 in the format PDF/X-1A. This format needed by a printing office to print the file. The strange thing is that Reader opens older PDF files exported from CorelDraw in thsi format normally without the error message.
It happens only with PDF exports made after the Reader update. CorelDraw settings are as previously used.
Exports in other formats, other than PDF/x-1, X-1A and X-3 open normally. How to solve this??
