Hi kailynm,
"the file or directory could not be found" error means your given iframe source has problem i think. Please cross check carefully like 'http', 'https' or the path you given is correct or not. If the source is local, chek that also. Better visit that URL/source first, if it really exists. Finally follow the things i shared and also the doc from Flexslider. Hope you will get solution!
