Buttons stacking vertical after update. Previous version available?

I use the shortcode to display my buttons on slide pages. After the update, my buttons are stacking vertically.

Is the last version of the plugin available for download until it’s fixed in 4.0? Everything was working previously before the update.

Thanks so much and love your plugin!
