Problems with modelling - Newbie problem

Hey   

     I just started using Materials Studio 5.0 a week ago. What I plan to do is include CNTs into the structure of a polymer. i tried the Amorphous Cell Calculation and Amorphous Cell Construction modules, included the model of a polymer and the model of a CNT in the composition/constituent molecules list. But when i hit run, an error pops up after about 5 hours of ''running'' as the status !!!! Please help.
