The sleep time corrected the selection errors we got before (err 32 and not not enough memory) There is another situation where er 32 occurs and that is when there are too many springs. Usually that is the case when there are many layers ( or strands) close together, Most of the time I can fix that by lowering the vertices neighbor distance in the (hair or cloth) parameters. This results in fewer springs

Make also sure that you wait long enough before you go to the next step. Look at the poser preview window - the cloth simulator will create a new prop and will update the poser scene with that new prop - you will see it appear and have the textures and transmaps applied. When you see it appear and is completely loaded, then go to the next step
