arcgis 10.2.1; cant export to PDF?

does anyone else's arcgis 10.2.1 crash every time they try to export a PDF?

the same mxd's made PDF's just fine in 10.1.

any ideas?

thanks,

max

edit: figured it out... the default export style is a "production" pdf (whatever that is)... if you switch to a normal pdf no more crashing.
