[Therion] Problems with export pdf file

Hi! I have been using Therion for some time and during surveying one map I met a problem with exporting pdf files. Everything is OK when I'm exporting lox file, even with full models of corridors, but during exporting pdf file the error has occured: ##################### end of pdftex log file ##################### C:\Program Files\Therion\therion.exe: error -- cp exit code -- 1 writing xtherion file ... done What does it mean and how to resolve this problem?
