Hi!! I was using RSLogix 500 starter software for Allnen Bradley 1200 PLC. But few days back the PC in which this software was installed had crashed beyond recovery. Now when this software is reinstalled into a new PC, i am facing activation problem. Following the FactoryTalk Activation manager leads to "Validate Activation" option. Once the serial number and product key are given, it shows that i have zero downloadable activation left. I am not sure what to do now. Please guide.
