Broke update!

Hi,
i was using wp pipes since 2015, but today for some unknown reason it update, all my pipes missing, and i cant create new one, duo to screens problems, dont open options of the processors. I know my wordpress is really old, but with this theme i cant upgrade the wordpress version for compatibily reasons. I want to know if i can get an older version of wp pipes so i can run it again on my installation, or solve this problem. I have on this image below two processors: slug and fulltext.
By the way it is a great plugin.
Image of the problem:
