Happyforms update broke my site

On Feb. 23 I received an update notice of an update to “Happyforms (free) version 1.25.1”. I didn’t check my site immediately, but noticed a few days later that it was down. Trying to visit the site resulted in this error:

Warning: require_once(/hermes/bosnacweb05/bosnacweb05/bosnacweb05al/b688/nf.ptay/public_html/number_one/wp-content/plugins/happyforms/core/helpers/helper-activation.php): failed to open stream: No such file or directory in /hermes/bosnacweb05/bosnacweb05/bosnacweb05al/b688/nf.ptay/public_html/number_one/wp-content/plugins/happyforms/happyforms.php on line 114 Fatal error: require_once(): Failed opening required ‘/hermes/bosnacweb05/bosnacweb05/bosnacweb05al/b688/nf.ptay/public_html/number_one/wp-content/plugins/happyforms/core/helpers/helper-activation.php’ (include_path=’.:/usr/share/php’) in /hermes/bosnacweb05/bosnacweb05/bosnacweb05al/b688/nf.ptay/public_html/number_one/wp-content/plugins/happyforms/happyforms.php on line 114

Yesterday I received a WordPress recovery link by email, but clicking it resulted in the same error. I contacted my provider and they disabled the happyforms plugin. My site is now back up, but customers can’t contact me. I’ve logged in to my site’s File Manager and looked at line 114 of happyforms.php, but from that I can’t tell what to look for next. I’m not a Web developer, so any help resolving this would be greatly appreciated. Thanks!
