Just upgraded to a new 27" quad-core iMac and migrated all of my files over. I was in the middle of a huge InDesign project and have over 30 InDesign files that I created on my old 24" iMac. Now, here's the problem: When I open any of those InDesign files on my new iMac, it tells me that two fonts are missing: Gill Sans (T1) Bold and Gill Sans (T1) Regular. How that happened, I have no idea. But those are the two fonts I use most throughout all 30 files, which results in 199 errors for each file because of those two "missing" fonts. Now when I try and change the font to Gill Sans Bold and Gill Sans Regular (not the T1), it's identical, but the spacing is a fraction of an inch larger which results in dozens of words on each file being pushed to the next line, obviously resulting in chaos. Anyone have any idea what's going on here and how to rectify it. On my 24" iMac, I was using Leopard and now the new 27" I'm on has Snow Leopard if that makes a difference with the installed fonts -- but all my files were migrated over via auto Firewire transfer so the two systems should be identical! I'd be super appreciative if you could help because right now, I'm screwed!
