Ezreal, Caityln and Ezreal Level 5 mission reward client bug.

I completed a game at level 4, getting the xp required to reach level 5. As a reward i choose between the champion reward of ezreal, caitlyn and tristana, however i am unable to select any chamions to allow me to return to the home screen. I am only able to gain control with my mouse during the lower portrait of the champions and it doesn't let me select any of the 3. Tried reloading client 5 times and returns me to the screen. I am unable to access this account in this state.
