Poor client reliability in Champion Select

Recently, my client would crash most of the time when I tried to open the hextech crafting inventory. This is relevant to this post because, in order to fix it, I repaired my installation last week. This means that it should be in decent working order.

Within the past week, I've experienced several crashes of my client while in champion select. This is a particular bummer in ranked, because you automatically get docked LP and get a time penalty, because you have to lock in your champ (had it crash a couple times while hovered, if this wasn't a requirement i'd have made it in game fine).

Is anyone else getting this a lot, too?
