I can't buy champions!! Help me

Whenever i try to buy a champion it just gets stuck at the screen that should be telling me how much RP and BE the champion costs, however it doesn't. In fact it doesn't even show up so i can't buy the champion. The only way i can get new champions is by getting champion shards. Please help me! [SOLUTION] It seems that you cannot see the price for a champion unless, you have enough BE or RP to buy them. Kinda bad patch but it is how it is.
