None of the Premiere versions, or programs, work well on networkds. You will have better luck if you store your Project on an external, with the proper drive letter assignation and the media files, things will be better for you.
I use a 2TB external with the PREL (Project files), all media and these are each assigned the same drive letter in the OS of all of my editing machines. So long as the drive letter does not change (you MUST set it in the OS of each machine), things work perfectly.
You may wish to contact Adobe Tech Support, regarding the school's network, most people have insurmountable difficulties trying to do so.
Good luck, and please report back, as schools often attmept to use Premiere and Elements on any network.
