Upgrading is not a straight forward process, if you changed a lot in the menus und widgets. Otherwise just download the latest plugin version and copy it to your projects Plugins folder like advised in our documentation. If you changed the design and some Blueprint stuff, I’ll recommend you to make a backup in a second project and copy it over to the new version.
I also recommend you to wait for the 4.25 version we will release soon, when Epic is ready. We fixed a lot of bugs and did small fixes here and there.
