InDesign CS3 data migration issue
I had a crash of the motherboard (display/graphics/video card) on my old imac. I bought a new (used) one with an OSX similar to what I previously had to make sure I could retrieve files etc. (I didn't need to go too new for now). I did a data migration, and everything came across, but the InDesign application said that it was 'missing files': (/Library/Application Support/Adobe/TypeSupport/.../ROMAN.TXT) and needed to be re-installed. I have no idea on God's good green earth where those disks might be. I used InDesign to design my book which was published in November in the UK. I need the files to design the sequel. I am stuck. While I am happy to move up to CC, I just bought a used imac that may not be capable of running it. I was happy with the imac I had. As I said I was afraid to go too new for now, because I needed to be able to access what I already had. Any suggestions?
I did a 'chat' with Adobe. They could find my older version, but no registration for my CS3 version. I know I bought it, it is on the new 'desktop'. I just can't open it. Adobe says that without a serial# I am stuck. If I remember, when the application launches, the serial number shows up in the launch box. With a crashed video display - I can't even see that number.
