You are trying to create the pkg without the rest of the files....
psn_package_npdrm folder should contain the files it came with + the BLES01287 (or whatever game you use) folder
The BLES01287 (or whatever game it is) folder should contain ICON0.png, PARAM.SFO, PS3LOGO.DAT and USRDIR (that should have all itīs files in it...)
EDIT: Tested with UP0002-BLUS30838_00-MW3P000000000010-A0102-V0100-PE.pkg and decrypted and packaged fine.
I havent bothered checking (sorry) if something needs to be done to the default.self also.
