Unhandled event loop exception error [message #1749831]

Hi
I wanna to work with this tool [1] of epsilon. When I right click on my .etl file and click on each of 3 sub menus of Epsilon Haetae, I have "Unhandled event loop exception" error.
I test it in 3 systems and get the same error. What can I do?

It's not an Eclipse-hosted project. You'll need to get support from that project directly. Perhaps open a Github Issue against the project with the stack traces you find in the Error Log view.

Since the author don't get this error in the same version of Epsilon but I get, I think this problem is not related to the tool. And something is wrong with my eclipse or system. I think Maybe I must change setting or some file of eclipse.
once when I get this error in another tool, When I scan my PC the error is removed. But this time not.
