This is rather desperate. I turned on my work computer today and went to open InDesign (CS4 on PC) and it wouldn't open like usual, we've had this product and have been using it for some years. It has now prompted me with:
1. I'd like to use this product as a trial
2. Enter your serial number
This has never happened before. So, I found our box and entered our serial number and it wouldn't accept it.....???
Really frustrating as I need to use it and am on a deadline.
Any help would be really great!
Try using System Restore to go back a day or two.
