DRM Testing in Symbian OS ver8.1b - DCF File, DRM File

I need to test the DCF/DRM file in symbian OS ver8.1b. Can anybody tell how to test the DCF/DRM file through symbian OS ver8.1b simulator. Currently, i am using sample WAV.drm(given by symbian itself) for testing. While opening the file through Techview getting error (Error code -1). By debugging, while opening the file rightsexists getting the error(Kerrnorights - rights not found).



I am able to see the Content header and content data size but decryption will not happening.

Is there anyother way to test the sample DRM/DCF file. I understood the flow from the document but while i debugging getting some error. I am totally new to Symbian and DRM/DCF.
