Multiple questions

Hi, we have just purchased the Fundingpress and don’t have the child theme, missing slider and no option where to set the activation code. I quite go the steps how to update after, but still the starting point is missing for me. Our version is V=4.1.9. Let us know where or how to start, please.
1. We would like to switch to the child theme, but it’s not part of the zip file
2. We would like to update to the latest version but the forum doesn’t include the full update only note about to delete the theme and upload the zip file again which just doesn’t seems to me as an regular update
3. We’re missing the Layer slider file to be imported to the site [layerslider id=”1″]
How to manage local curency payments within the configuration – guidelines or link How2 would be great. Thank you.
