And here I am...
funny what Graphisoft told you... it should be interesting to know who (from GS I mean) told you such thing because the student versions of our add-ons are only for ArchiCAD 11... before there were no student versions!!!
What Karl supposed was right:
"So, an add-on that was working for one license will NOT work with a different one"
That means that if you installed a normal-commercial version it won't work under ArchiCAD Student version.
The only way to get the student version is to contact GS... they are the only Distributor and they are available from the same web site from which you download ArchiCAD student versions (together with Artlantis and the CADimage tools).
From what I know there are some country which refused to distribute our add-ons so they are skipped from the EDU Registration We page.
