Hi, We purchased Maxim a while back and currently use v5.12. We've just upgraded to ACP 8 and now it is asking us to use at least Maxim v5.22 (6 recommended). Can you tell me how much it costs to upgrade to maxim 6 please? Our current license was purchased by my colleague Don Pollacco and it registered to his old email address at our old workplace (d.pollacco@qub.ac.uk). We currently have no access to that email account so do not want to use the online tool to request an upgrade as we won't see the email response. I can provide the serial number via email if required. My email address is j.j.mccormac@warwick.ac.uk Cheers James
