I'm running Vue 4.22+Mover+Poser5 on one and 4.53 Pro on another machine and all works fine for me. Maybe an update from 4.2 to 4.22 can solve the problem, btw. it's very solid. You can also check if your connection to the network drive, where poser is installed, is permanent, which means that you have a drive letter for this connection. I already had problems with some programs pointing to a network drive wich was not mapped to a static drive letter. I'm also not sure which version of Poser you actual use. Hope this helps. Norbert
