The Poser 4.03 patch, available from the Curious Labs website, fixes the "Caught C exception" error. It doesn't matter if you're using the Metacreations or Curious Labs version of Poser. It's the same program. CL just took it over after Meta dumped it and in fact, almost all of the staff at CL are the people who developed the program from Meta in the first place so they've been with the program from day one. They provide support for Poser 4 in all its incarnations. As for the out of memory, well, that's sort of the catchall for when poser doesn't really know what the problem is which, again, is most likely tied into the "caught C exception" and will probably clear up as soon as you apply the patch. That's how I fixed it when it was happening to me. Kate
