I think people should know that you can get locked out of the Nusphere IDE when you do a Nusphere update ... and it may take a long time before they correct the problem. I purchased Nusphere IDE a few months ago, and they have a free point release that i installed today. It rejected my serial number and now I can not use the IDE at all and they still have not gotten back to me to correct the problem. For me, I would not have purchased the product if I knew this problem could occur as I can not do any work until they decide to get back to me.
