Creative Mail Crashed My Site

I followed a Jetpack recommendation to install Creative Mail and it crashed my entire site with the following message:

Parse error: syntax error, unexpected ‘)’ in /homepages/27/d624866202/htdocs/clickandbuilds/WisconsinTaiChiAcademy/wp-content/plugins/creative-mail-by-constant-contact/src/Managers/EmailManager.php on line 414
There has been a critical error on this website.

I can’t even get in to my admin to try and fix it. I accessed the admin page from WordPress.com and deactivated Jetpack as advised but it hasn’t fixed anything.

My site is my business and every day down costs customers – how do I fix this???
