How can I use MC Edit 1.7 in Minecraft version 1.13.1?

In 1.12.2 I started to build a building and now I have ascended to 1.13.1. When I wanted to use MC Edit 1.7, it did not work anymore! How can I still use MC Edit 1.7?

There's no MCEdit 1.7, there's MCEdit for Minecraft 1.7-1.11. Officially, not even the Minecraft 1.12 is supported. Minecraft 1.13 as well not.

You can try MCEdit 2 beta 14. But not more.

OK.
