I'm a newbee to the Lon world. I have been using LNS for a while and I recently acquired an iLON 100 e3. When I loaded the software it loaded a trial copy of Contribute 3.11. Adobe sells Contribute 4 now. When I need to purchase Contribute which version should I use. Will Contribute 4 work. Adobe does not sell Contribute 3 anymore so how would I even activate it. Looking for some guidance before I step into a big hole that's hard to back out of.
