[Theme: Andrina Theme ProTheme] Slider Images Disappeared

Hi All,

First post here. I appreciate any assistance you can offer!

I just started using WordPress for the first time managing a church’s website. On the Andrina Theme ProTheme I’ve been changing the Features from the WordPress admin in Appearance-> Theme Options -> Homepage Settings. All of a sudden, all of the Slider images that had been previously set up have disappeared from the website. All of the image URLs are still in place in Appearance-> Theme Options -> Slider Settings.

Thus far I have tried:
-downloading each individual image and uploading it manually from computer as Slider Image 1, 2, 3 etc
-backing up then updating to wordpress 4.2.2
-deactivating all plugins then reactivating one by one

Anyone have any ideas what’s going on? Please be gentle, I’m very new 🙂
