Affinity Publisher is not exporting my file into PDF

[Angie-ME]

Hi,

 

first up, sry if my english isn't perfect since i am not a native speaker. 

 

Basiacally Affinitiy Pusblisher stops exporting progress after maximum 10% if at all. it takes a few minutes to even get there and after then nothing happens anymore more not even after an hour. 

I got a fairl large file, in the sense of dimensions. Its a 3mx5x Billboard. and ofc. it has large pictures with large resolution and 300 dpi. The document is converted to CMYK and i am using ISO Coated V2 300% ECI profile, while exporting i use the PDF/X-1a:2003 Preset. 

I tried switching in the dokument preferences from "linked pictures to embedded Pictures" but that doesn't change anything. 

 

I mean i would understand if the exportin process takes a while, but well...it basically gets stuck. If i abord it, its aborted imediatly.

 

Any Ideas? My client is already asking for the exported file, and i don't know what to do.

 

The specs of my pc schould be fine too

Never mind, pls delete...i had to allow affinity to use the whole 32 gig ram...and well then it was done in Seconds...
