The method : 1/ I uninstall Poser 5 (big, big job because i do backup my huge poser files libraries.... :o( 2/ I install Poser 5 CD, i start poser 5 AND I obtain unlock Key from Curious labs site. 3/ I install Poser 5 sr3 update. All is ok. 4/ I start Vue AND .... :o)) After Vue had located poser.exe no message "invalid serial poser number" YESSS !!! 5/ I can import PZ3 ! The difference with the problem situation, is, this time, i install the poser "unlock key"... Life is beautiful :o)) Thanks again all the people (Specially Gebe and Steve Bells) that help me !
