I have made a poster (100cm x 120cm) and it looks fine. But when I export it to PDF I get the message "Out Of Memory".

I have tried to reduce it to 50% but I get the same message.

Since the poster is kind of big I have chosen 300 dpi - and I know that's a lot.
Tried saving under new name - but the error occurs again.
Tried different settings when exporting - same error.
I have at least 20 GB free space on the hard disc.

I am running XDPX10 and earlier today I upgraded to the latest version dated Aug. 8th 2014.

Does anyone know what I can do to export the file to PDF without this error?

Thanks!
