Store Bug?

I'm not sure what's wrong with my client because it's been acting up lately but it's completely impossible to do anything in this shop. I press Codes and try to enter my RP card but it doesn't do anything after I enter it and i can't even buy skins, champs or gift anyone. I was going to try to repair my client but it would likely be a waste of time since I've done it plenty of times trying to fix my disconnection issues. Just wanted to see if anyone has a similar problem or any known solution. Any feedback would help, thanks.
