Hi, I updated AI. 2 days ago and I can't open it.
It says something about some plugins... but I haven´t done anything different.
It can't load the plugins. Usually this happens when something has gone wrong when installing.
When was your last computer reboot?
Did you reset preferences when installing?
Hi, i just reboost it, and nothing....
I did not reset any preferences, I just did it thru creative cloud as usual.
In Creative Cloud resetting the preferences needs to be set as an option.
You can try if it helps by renaming the folder as described in here: https://helpx.adobe.com/illustrator/using/setting-preferences.html
Sorry to hear about your experience. Would you mind sharing the version of the OS?
