Export to PDF problem

[Rik]

Hi Xperts.

When I try and export my drawing to PDF, I run into problems.

First, the exported pdf was about 6Mb in size.
I then got rid of all the things I was using to make the drawing as I wanted it.
I removed any transparencies I had added. Removed any feathering, etc...

The file size might have got a better, but there is still a problem.

In the .xar file attached, you will see two gold rings with diamonds inside them.
The reason for duplicating the gold rings is to simulate the fact that I've got more stuff to add to the drawing.

when I try and export this to PDF, on one PC, I get an error that says:
Out: An unknown error occurred during linearization.

On another Laptop, I get an error that says:
PDF Filter: PDFNET error: , line 0. bad allocation

Any ideas as to what to do, guys and gals?
