Hi Patrick,

Are you still having trouble? I was just able to retrieve ADDE imagery, no
problem.

At any rate, here is our stock response for anyone who runs into this situation.

There are several ports you need open in order to run the IDV so that it may
connect to different data servers. In general, ports 112, 8080 and 80 are
required. Port 112 is required to be open for ADDE.

Best,
