unspecified error

So after not having played for about 2 months, I decided to get back into LoL just for fun. As I was updating last night I got "Unspecified error, please check logs for more information"

I have done a virus scan, used CCleaner and deleted my solutions in RADS (The patch is downloading now) and reset my router. Is there anything else, if this does not work, tha I can do?

EDIT: I am on windows 8 haven't downloaded windows 10 yet.
