Your Illustrator build has expired

[juisdy]

my illustrator beta v.25.5 not working since v.26 released i can't open my files so i decide to install the older version which is v.25.5 but it said "Your Illustrator build has expired"

Yes, same for me, I installed the new beta version, 28.0.0.7 and still get the same message!

Illustrator (beta) 28.3.0.55 has expired.

Illustrator 28.3 has expired... only just updated it. (Mac M1  Ventura 13.5.2)

The official 28.2 release works fine, so I don't have any problems working, it is just that I wanted to point out that the latest update isn't working.

Same, V. 28.3 of course in a deadline rush and now the software isn't working. Going back to 28.2 standard Ai to get through the workload.

I don't want to keep banging the same drum, but it's unbelieveable to me that people use the beta for critical work like this.

Same thing happend to me. It was open in the background (Mac OS Sonoma 14.3) then suddenly this error message pops up.

This happens with Illustrator Beta (28.2).

Uninstalling and reinstalling doesn't help.

I am also having this same issue right now.

Illustrator (Beta) 28.3.0.65 has been released and is available again.

As already said by others; never use a beta or prerelease version for serious work. They are there to test things, detect bugs and get feedback.

Always have the latest regular version installed for your daily work (yes, you can have the regular version (at this moment 28.2) installed as well as a beta version on the same system).
