I just tried a quick Aiko character saved from Poser 6, with external morph targets off (not an option in Poser 5 anyway) and file compression off. It took longer to load than the base A3 but it did load. I assume poser is happy to reload your saved files? Have you actually downloaded a fresh copy, or are you using the original - it sounds unlikely that an error could be present and yet let it install, but it's possible. I think all I can suggest is contacting DAZ suppport
