Hello,
i had this problem when i used it last time, theres an easy fix theres no problem with the account or whatsoever but must be a followliker bug.
After e-mail verification just right click on the account and hit RESUME after that it will resume and re check e-mail verification and work normally
Actually that does not solve the problem. May be you got lucky in your case. However, the problem is that FollowLiker needs to develop a functionality of accepting a new request added by Instagram. Once they develop it, it should be fine and I guess they are working on it.
