Postscript parsing error on the Prinergy Evo 6.0. Need help.

When I try to convert some postscript files into pdf format using "Refine to PDF -Factory",
some ps files works fine but other don't.
I cannot convert any ps files created by the Quak Express, always fail.
The error is "Unmatchedmark:OffendingCommand Counttomark"

Very strange errors. I checked the "Refine to PDF" template as well. Just used the default one. Are there anyone who can help me to solve this problem?
Thanks in advance.
