Cannot open Runtime/libraries/character/people/donatelo.cr2 this sounds like when you unzipped the file you unzipped it maybe to the path say like you unzipped it to the characters folder and it left the path in there. something like Runtime/libraries/character/runtime/libraries/people/donatelo.cr2 check your character folder and make sure you don;t have subfolder under the other subfolders. In poser 4 you can only have 1 level of folders under each main folder.
