It's submitted. It's just like pinging the tanki devs, so they can know your IP address & then compare it with the IP address that your account was created & played. I hope you opened the link with the same PC you used to play tanki

If you're using playing the game via a web browser, clear browser cookies & cache.
If you're using the client, use this guide to clear client's cache. 
After clearing cache, try entering the game again (note that this might take some time as you cleared cache, but not forever)

You need to open Tanki in HTML 5 (via a web browser or the HTML 5 client) and then click Shop. The first section of the shop is orange colored & it's called The Showcase. You can find skins, kits with discounts, free 100 crystals etc in showcase. There are about 1 or 2 kits in showcase that can be bought with crystals. New kits come to the showcase & old ones leave in every 12 hours. You can see a countdown under every item & after the countdown ends, that item disappears from showcase. You must be really lucky to get the kit you want from showcase for crystals as there are many kits & hence the probability of you finding the kit you want is very lesser
