The problem is that I cannot open a p3d file in oxygen2light. I depbo'ed the data3d file, then unencrypted one of the p3d's with unpack-sqm. When I try to load the unencrypted p3d it returns a "load error" message. Some of the p3d's seem to load OK (e.g. Makarov Pistol from Kegety's Russian Weapons Pack), but majority of the files fail to load. Can someone explain this to me? Thanks in advance.
