problem with Coreldraw x7 export to pdf crash

Greetings,  I have a problem, with Coreldraw x7.  When I try to export to pdf, the program crashes.  

Coreldraw x7 says it is up to date.

Windows 8.1 is up to date.

I tried changes the colors to CMYK and RGB, but it didn't help.


It does warn that fonts are too small....


If this has been answered already, could someone direct me to the post.


Thanks
