Uncaught Error: Class "TC_Event" not found

[onmouseout]

Hi Roadmap studios, the plugin would be great in my installation - its somehow state-of-the art and im wondering why tickera isnt ofering something out of the box. However, i installed the plugin and created all of the certificates and keys.
The URL to the Apple WWDRCA was updated to:
https://www.apple.com/certificateauthority/AppleWWDRCAG3.cer

After installing and setting everything up, the checkout process breaks at the point where the Pass-Entry is created. The following error is thrown:

It looks that maybe something has changed in tickera. Can you have a look?
