Thank you for all your replies a lot :-) Note that the error was occured after second load of the file. When I loaded the Characters/s from Library 1st time, things were OK. By the way I ve got many memory troubles with my PC after upgrade to Athlon XP2000+ . Although the working was speeded-up, many progs started working pretty strangelly, some apps frozed during loading and some other progs when running. The processor started to freeze at cca 60C and 3rd day of usage totally collapsed. I ve changed procc. back to Duron, but some troubles are continuous, eg. the Poser one mentioned above (I use mainboard MSI K7T266Pro2A).
