If you have an older version of ADIsimPE it may have expired. You can find the latest updated version at www.analog.com/ADIsimPE
if you do not update the software the folowing messages will appear.
"You will not be able to run any simulations"
When trying to update the software through the Help "Check for Updates" the application may not be able to find an update and the message "Could not establish a connection appears"
This are indications that a new version needs to be installed

One comment here is that I found that I had to uninstall my previous version of ADIsimPE in order to make this update work for me.
Thanks for the great support of ADIsimPE!
