Did you fellows every get Reposter working properly for you, or is it still not working for you? What about the Autoposter? Does that work for you? I would make sure that Autoposter is working properly first, because Reposter depends on the same account information. In case it is of any help to you, Reposter is working partially or fully for me for the following social networks:
Flickr = working
Instagram = working
LinkedIn = working
Pinterest = working
Tumblr = partially working
Twitter = no image being posted
