There were a bunch of in-program alerts and emails in late 2023 telling us to be sure to update and log on to tax years 2016-2022 before year-end in order to maintain the ability to log on because of some security changes that were being made.  Here's a link:  https://accountants.intuit.com/community/lacerte-tax-news-updates/discussion/action-required-securit...

If you did those and you're still not able to log on to 2022 try running the Lacerte Tool Hub.
