Login wp-admin, go to “BM PageBuilder” on left bar, Paste the key.
Note: if there is not the option, please go to themeforest download the Air theme, find :/air-theme/functions/plugins/bm-pagebuilder.zip, login wp-admin of your WordPress, re-install the BM PageBuilder(remove the old BM Pagebuilder firslty)

It will not remove the content built by BM Pagebuilder already.
Be safe, still suggest you make backup(install a backup plugin to do it) before removing any things.
ps:I checked your wp-admin, there is “BM PageBuilder” on left bar, it isn’t necessary to re-install the BM Pagebuilder.
