A weird prblem, no .pln or .dwg.

[Anonymous]

Hi guys, i'm a student and learning ArchiCAD v11.

Recently my friend discover a wired prblem in his archicad (New Zealand educational Version),

and that is: he can't open or save files such as .pln .dwg.

Those type of file disappeared from his archicad!
Tho he can create a new project when opening archicad, but can't save it in .pln or .dwg.

however, i don't have such problem (i'm using international edu version)
would the different versions be the cause?
or any idea what caused this?

my friend's computer spec:
OS:Windows Xp SP2 English version.
videoicard: Nvidia 8600GT.
Motherboard: Gigabyte GA-M56S-S3
Cpu: AMD AthlonN64 X2 4200.
Ram:2G DDR 800.

To clarify: there is only one installer. During installation you choose commercial (when you have a dongle), demo or student (which both require a serial number).

Files created in the EDU version are fully compatible with the commercial version and vice-verse, except that they have an embedded watermark. Whenever you open a file in the EDU version and save it, the watermark is embedded. It can not be removed.
