Hi,
Sorry for the issues you are having.
We are unable to provide tech support in the Pre Sales Forum please post in the WordPress.org Support Forum for the Events Calendar with issues:
https://wordpress.org/support/plugin/the-events-calendar
or sign into your account here and post in the Pro forum.
This is the first we have seen issues reported with 4.1.1 and I am running it on all my sites without issue as well.
It could be a conflict with something else, you can review our conflict guide to see if that helps you out:

Thanks
