i’ve had this same problem on several occations, most time i had to reload my cs4 for it to be resolved.
*you did not state your memory size,i found out that if a memory is low or bad it halts prgress.
*most times while my project is loading i access task manager and increase the priority of my importer process to real time while stoping some programs that are choking up memory space.
