If you are not the owner of the software (to whom it is licensed) you won't get anywhere with Rockwell. Whoever you purchased the CD from would have to notify Rockwell that you are the new owner of the software. In the past I have seen this done with a fax from the owner on company letterhead. You will also need to get the activation disk from them, otherwise they would have two activation disks out and only sold one package, so don't expect to have Rockwell send you one. I don't see any value of just buying the CD unless it was a newer release than a package you already had, which is not the case if you don't have an activation disk. You would be better served in buying a full package on Ebay or the lite version Rockwell sells. Good luck
