DD12 licence number rejected when installing v12.5
Can someone please tell me what gives with DD12.5. I want to get it installed and since I have DD12 I am led to understand that the one licence number should work for both DD12 and 12.5 -- but it doesn't, it is resoundingly rejected. Do I need a new licence number and if so how do I get it? I guess its a case of contacting support. Any help would be most appreciated. Thanks.
