SugarChimp

Hi, We tried to upgrade SugarChimp from 7.7.1 to the latest version 7.8.1 but during install the system crashed our on-demand instance, it was totally unusable. Sugar support stepped in and managed to get our system back on line. They put the following comments in the ticket once it was back up, our installation was unsuccessful and we are seeing errors in the sugarlog: _**Thanks for reaching support. I was checking and the issue is that in the file "modules/SugarChimp/includes/classes/Mailchimp/API.php" there is a request for the file bellow that does not exist: modules/SugarChimp/includes/vendor/Mailchimp/MailchimpV3.php By commenting this line the instance access was restored. Can you please confirm that your access is restored? After that, you can redirect this error to the SugarChimp team to see if they have any further advice : PHP Fatal error: require_once(): Failed opening required 'modules/SugarChimp/includes/vendor/Mailchimp/MailchimpV3.php' (include_path='/mnt/sugar/7.7.1.0/pro:/mnt/sugar/7.7.1.0/pro/vendor:.:/usr/share/pear:/usr/share/php') in /mnt/sugar/shadowed/psigroup.sugaropencloud.eu/modules/SugarChimp/includes/classes/Mailchimp/API.php on line 12, referer: https://psigroup.sugaropencloud.eu/**_ Errors in the sugarlog are: Tue **_Feb 14 09:13:28 2017 [23826][1][FATAL] Job afa61448-f295-11e6-87c3-06e555942243 (SugarChimp) failed in CRON run_**
