Thanks sabatica, maybe there was some minor misunderstanding. Indeed I confirm I have the same problem of the original post and have a trial version of Iwork and purchased keynote. You have to acknowledge that the previous posts and maybe also mine were a bit confusing 😉

The original post was regarding continuing to use an expired trial version of Keynote which obviously wont work after the trial has expired.

IF you are using a TRIAL installation then you have the same problem as stated earleir.... if you have a trial you do not have a serial number.
Thanks a lot for your help. One last question: If I reinstall keynote do I have to insert the serial number? You recommended to specify the right version of keynote... what do you mean by that? Thanks again for your time.
