can't enter game

every time I try to recconect league crashes and bugsplat opens and when I restart it still does. This will be the third promos I've lost from this and to stack that on top of unbalanced teams I've essentailly lost almost all my promo's. exept for two so far. and it's really frustrating because our team comp was really good this game and the enemies was so bad that it would've been almost impossible to lose. Then last promos I did in preseason I was playing with diamond and master players and doing well until you reset the system and now im playing agaisnt plat players while my team is gold every game and there impossible to carry.
