Client crashing while updating.

So i recently downloaded League of Legends,installed it and opened the client.At first it's all normal.It updated the the client and then it goes to downloading the patches.It gets to around 44-60% and then it gives me an error.Over the last 3 days I haven't been able to update League.So,if anyone has any idea how to fix it,I will gladly try it.Also i forgot to add,I have redownloaded the League installer at least 3 times and every time it's the same. Thanks in advance. :)
