thanks.there are 3 wibu shown when adding hardware - wibu-box/M ( computer crash), wibu-box/U- works but crash when archicad is opened.
i've uninstall and re-install archicad and the wibu driver over 3 times now...
i've no problem with wibu key from 94 to 2002 until i upgraded to version 7 ( from 4.5) and now just 5 years, i've problem with wibu key.
i'm desperate now!
