P4 uses rsr images instead of png. You can convert png to rsr with P3dO Explorer ( follow the link). And the newer version error is because in the pz2 files it probably says version 5. You can find this in the beginning if you take a look at the files in a text editor. You can change it to 4 and it should work fine: version { number 4 }
