Okay I have a copy of Indesign CS (v1) which I am using on a G4 and on my Macbook. I work between the two computers and need files to be openable on each one. When I upgraded to the Macbook, the Indesign off of my old G3 laptop was transfered. It worked fine until a month ago. I went to reinstall Indesign on my Macbook and it keeps giving me a "The Serial cannot be recognized." (but in Japanese.) So why after working for 4 months did it stop working on me? Why will it not let me reinstall? Why is it not recognizing the very very good serial written on the CD case? This is really starting to piss me off. NO MONEY TO BUY NEW VERSION EITHER. HELP!!!!
