try to instal some newer MaintenancePack for NX10 or better higher versions - 10.3 etc
NX10.0.2 had issues in the early releases, if you search for this "Re: SFB-NX-9430 - Postbuilder 10.0.x issues" there is a useful download as @Juraj says if you are able to upgrade NX to the latest Patch or even better upgrade to NX10.0.3MPXX?
If you go to the GTAC page and have a current access web key you will be able to download the latest and greatest http://www.plm.automation.siemens.com/en_us/support/gtac/
You can download updates from the Siemens GTAC Support site. If you need to stay with NX10, go to Download and Upload files, NX, Product Updates, Maintenance-release, NX10, and browse to nx10.0.3. Then I would go to Maintenance-pack, and download the latest nx10.0.3-mp14.
