Deactivate Acrobat X Pro

Hi, Guys! I'd like your help because I have an Acrobat Pro X and I'm not getting use it due to have already registered over two activation and I'm receiveing a message that I need to deactivate in another where this be activated yet. However, I'm not have access to this computer due to the damages done to HDD where the App was installed. So, how can I deactivate all previous activation in order to restart the Acrobat Pro in my new SSD under the same serial number? Thanks in advance for all.
