are you using the network version from where you teach?
if so you need VPN to get to the server that has the network license manager on it.
you also need the serial number and the port id.
it would be best to talk to your it department to see if this is allowed.
I work for Arizona State University and that is what i have to do.
I beleave SW won't give out stand alones if there is a network version, they may send you a student version but somethings are locked out, like all the translaters, pdm and toolbox.
I had done that last year but when school ended so did my access.
are you still in the program, if you arn't they may have cut your access to the server, that is what we do here otherwise the there wouldn't be enough seats to use.
