Theme Issue

I have this theme: https://themeforest.net/item/exposed-responsive-wordpress-photography-theme/5496096 which I know is a premium theme & it is no longer supported.

The reason I am posting here, is because I can’t even access my WordPress admin with the theme active now. If I deactivate it thru FTP, WP admin works again.

Are there any things that I can try to keep this site up & running, while still running this theme? I don’t necessarily want to have to build a new site a this time.
