I purchased Carrara5 Pro yesterday from Daz. (Download version.) When I attempt to open a PZ3 file uising Transposer and following their instructions, including opening the Poser Executable file, I get an error message that says  "An unknown error occured while executing open". Has anyone else had this problem? I'm concerned that my file might have been corrupted during download although there was no problem during that period.  Any ideas? Thanks for any and all help,
