[Plugin: Instapress] Feed is not mine

I am trying to use the shortcode to embed my feed on to a page. When I use my userid, it does not work. If I insert “myfeed”, I get a feed of someone else’s feed. I have also tried to insert the used id # assigned to my account by instapress. I have re-logged in my account, I have reset everything. I have verified that my theme can use fancybox settings. The same problem occurs.
