Instagram Update? Unfollow and liking hit badly

Hi I am using Instadub and just 2 hours back i noticed all my unfollow and likes actions are hitting errors. Its common to all my accounts. All the vps. Just the follow action is working starngely enough.
This is the error for all other activities:
ERROR absproc: Object reference not set to an instance of an object.

Has anyone else felt the same? Other softwares like follow liker and jarvee too facing the same issue?
