InDesign [InDesign trial expired within 24 hours of first being opened. What can I do?]

in addition to the info in Atul Saini​ 's link you can start a trial on another computer.  starting a trial on the problematic computer would require a hd reformat etc

Hi Simonab13153106,

As you have mentioned that you have installed trial version for InDesign and it is now expired, I would request you to check this link which talks about the reason why trial expires early: - Understand why Adobe trial software expires or ends early. 

Please feel free to update this discussion in case you need more information about this.

Thanks.
