Guild Wars 2

Hey I was wondering if anyone else ever had this problem

I tried entering the CoF explore mode today and it only gave me story option
I have done the story and opened the dungeon several times before
Tried relogging and restarting but it still won’t let me

Any suggestions? I would really prefer not to do story again because it was long and painful.

Are you sure you are on the character that did the storymode??
You need to unlock explorablemode for each character separatly.
