I am trying to reload my PixInsight onto a reformatted hard drive in the same computer I had it. I still have my original email from PixInsight with my username/password/user identifier/activation code. After I (re) download the correct version of PixInsight for my OS following the link in the email and then I copy and paste my user identifier and activation code (the correct activation code for my OS) I get a window that reads: Authentication error. The server says: 'INVALID AUTHORIZATION CODE' -Yet all of this information was copy/pasted into the windows from my email. I am running Mac OS 10.6.8 and I know the version of PixInsight for this platform is unsupported. I would just like to get back to where I was before my computer crash - and then work on upgrading my OS since that is what caused the crash in the first place. Thank you for any help!!
