[Client] Enough IP to buy an In-game Summoner Name Change but it's still highlighted red

So basically whenever I try to buy an in-game summoner name change with IP, I can't. The IP amount is highlighted red, making it not possible to buy. I have restarted the client multiple times, and have uninstalled / reinstalled the game twice already + ran as admin every time. It say's when I click on the Summoner Name Change that I have 13,043 IP but I actually have 15K IP now (after playing some more games) and it's not adding anything to the 13,043 IP. Nothing seems to work. I really want to change my name please before it's taken.

Here are some screenshots of what happens. (In order) 1): http://i.imgur.com/QId4g52.png (I open store and go to account. Now as you can see it says I have 14,436 IP yet the Summoner Name Change IP requirement is highlighted red.(unable to purchase)

(Now I click on the Summoner Name Change and it says I have 13,043 IP (as explained above), but I really have 14,183 IP.)

3): http://i.imgur.com/15u2jbU.png (I put in the name that I wanted then clicked "check name" (It was available). I then proceeded to click "Unlock" and then the the error popped up. Saying "Unable to complete purchase. Please try logging out of the game client and re-starting it before attempting another purchase. If)

Is anyone else having this problem?
