I installed OS 9 this morning, and I downloaded the form to get OS 9 for $19.95 form Apple..(I thought it would be a rebate since I just bought the iMac DV SE. Now I realize that it's only that if I bought OS9 from Apple. So now I guess I'll just get the $20 off rebate for upgrading from 8.6)..Anyhow, to get to my problem..I tried opening the form that I downloaded from Apple in Adobe Acrobat, and I got the following message: "The application Adobe Acrobat Reader 3.0.1 has unexpectedly quit because an update to this software is required for compatability with the improved Mac OS file system. You should save your work in other open applications and restart your computer." I tried looking for Software Updates, tried reinstalling Acrobat from the iMac CD, but nothing has worked..have any of you had this problem or know how to fix it?
