Hi. I am temporarily using a borrowed laptop, because mine died. My old hard drive is in this machine but my parallels will not activate; This is the number in the activation window; 5a544578597a417a4d444a6b4d474d774d5467774d4442684d44466a4d446f794e6a646b59546b7859575a6b4f5463314f54497959575a6a4d446333593259315a57526d597a4d344d513d3d Can you help me get this working again. And, what do I need to do when I put this in my actual laptop replacement? Thanks for your help. Mike
