Greetings!

I'm not new to this game, but it said i would get an bonus reward if i finished - Conquest tutorial
An as i start of, they tell me to press "I" to get to the item store - And i'm like, sure.
But the funny thing is, i couldn't buy anything?
I could not even go out of game or do anything for that matter...

Here's a picture:
