Ok, about Vicky, the problem must be the number of huge texture maps that eat up all your memory. A workaround would be to either use lower res texture maps ( depends  on the ones you use, but Vicky comes with hi and mid res textures), or in your Vue preferences, disable background draw thread.

About your Aiko problem, did you check in your Poser preferences that morph targets are not saved to an external file? If so, change the option to keep the morph targets within the PZ3 file.
