X-Title Caption Convert Subtitles Offline

I installed X-Title Caption Convert and was able to convert my project with captions into titles seamlessly but when I sent the project to my coworker the titles appeared offline and we can't figure out how to get them to work. I had him install the program thinking there might be a plugin that was attached with installation but when he installed XCC on his computer he kept getting error messages and it wouldn't open successfully. So I guess this is a two part question. Do you need to install some type of plugin so the new titles I created through XCC will work on any computer and anything thoughts on how to get the program to successfully open on his computer. I have attached screen shots of what the subtitles look like on his FCPX and also the error message. Any advice would be helpful thanks!!

Ounce your titles are generated from X-title all you will need on the second computer is the same "title"that you used to process your subtitle.
On the other subject concerning the script error Andreas Kiel will probably chime in, but you do not need it on the second computer because now you only have TITLES to display.

Hi Logan,

You installed a very old version of X-Title Caption Convert.
Go to the app website

Hi Logan,

You installed a very old version of X-Title Caption Convert. That version won't run with Mojave. It also has some old version of the titles.
Go to the app website and download the actual versions both for the app and the title templates.

Since you have this old version already installed you must run the template installer before running the app.
