I'm sorry if this is either a dumb question, or not appropriate for this forum.  About a month ago, I purchased a copy of NI Pro Developer and Sound and Vibration Toolkit from NI.  It was supposed to be for a client, and a week ago, that client went bankrupt!  Here I sit with some expensive software, and am curious if I can sell this software?  I have not opened it up (it is all still sealed), not have I registered it, etc. 
Does anyone know if I can do this?  If so, any ideas where? 
Thanks for any/all help!
