I went ahead and deleted the Poser Pref file. So far it's working. I don't know what the pmd file (0x6080005ef600.pmd) - the one that Poser asks to locate every time I open my file does? I searched for it, but nothing showed up. I took out the pmd file that Poser creates automatically, which has the same name as my main working file. I am still asked to locate: 0x6080005ef600.pmd I would love to find out how to solve this! Thanks for everybodys feedback!
