Been using Revit ARch Suite 2011. Is there an easy way to tell if we will be able to upgrade it? It was won as part of a technology contest. It is the full, commercial version with serial #s and Product keys, etc. But we are not sure if it's can be updgraded... People have suggested "calling Autodesk" but that is not as simple an answer as it seems. Lots of resellers (none that we've worked with) and no "phone number" to call. Thx!
