I have just re-installed Actional Diagnostics on my PC and when I hit the activation page (http://localhost:8103/sos/v/pub/setup/license/activationRequired) I get this error:
Actional is no longer a tool owned by Progress Software - and the user groups forum might not get enough attention from the right people @ PSC.
You should contact your Progress salesrep or maybe technical support to find out what your options for activating Actional.
