PDF Export error Xara X10

[geckosoup]

Hello Apologies if this has been covered elsewhere. I have looked, but found nothing of relevance. I'm running Xara X10 on a Windows 8.1 machine, both the 32 and 64 bit versions. Both versions - in administrator mode and normal mode - give me the following error message whenever I try to export as PDF. " Serious Error from Xara Designer Pro X10. Access Violation Exception at 0X4C479042" The export will then hang at 21% - or some other seemingly arbitrary percentage - and I have to close Xara...sometimes with a force close through Task Manager. I've only just upgraded to X10, so don't know if this is a known bug in the software or if it's just local to me. Any help would be hugely appreciated. Thank you

If it helps any, the same file opened in Xara X9 - both 32 and 64 bit versions - exports to PDF without any issues at all.
