Saving Problem HELP!

[Xtreme43v6]

Hello all i found this forum on google and i hope you can help me out. I am a teacher and am trying to use Co Create Personal on one of my classroom computers. My school is anticipating buying the program next year so i have one student piolting it this spring. The one problem i have is saving. When the student goes to save the computer instantly freezes but if i log him in under a teacher account it saves fine. My network tech has removed all the permissions off the C Drive. What else can i try. I want to make sure this works in my school and network before we purchase it.
FYI i also tried saving it to a flash drive, the desktop and to the network. No matter where i try to save it on a student account it freezes.
Thanks for the help
