acf to acf pro – lost all my fields

Hi everyone,

i have recently installed the plugin ACF – basic, and have made many custom fields under two field groups.

I then installed the plugin ACF – pro and now i can longer see my custom fields, no groups, nothing.

However, they are still appearing on the site, except for one…

What on earth is going on?

thanks for any help!
