Articles 1.5.0 pl fails to install - how can i revert to previous version?

Just saw an update to Articles 1.5.0, and clicked to install. Install console showed following:

Notice "failed" message in last line. Attached is the full Console text.

The Package Management does not have "reinstall" button by Articles 1.5.0, only available options are "install" (which fails) and "remove" option, i'm afraid that if i remove it, it will loose all the data and templates i have configured. How can i go back to previous "working" version? Any ideas?

I am running MODX Revolution 2.2.0-pl2 (traditional) [ed. note: cesarl last edited this post 14 years, 6 months ago.]

The page itself in browser shows following text:

Fatal error: Call to undefined method ArticlesContainer_mysql::getProperties() in /home/philblog/public_html/core/components/articles/model/articles/articlescontainer.class.php on line 443

So I backed up Articles related stuff, just in case. Clicked "Remove" package button, and it let me re-install previous version. Looks like everything is back to where it was.

Articles 1.5.0 requires MODX 2.2.1 to run.

sorry. how did i miss that? THANKS!

I installed 2.2.0 and updated to 2.2.1. Installing this addon I first got a message about unable to unzipper quip.
When I installed it manually, and reinstalled the article addon I got the same errors.
