Patching Error For OCE On Mac

I have no problems with patching then getting to the login in client on NA when when I switch over to OCE the patcher client goes through thousand of files then stops then shows an error happened then goes to 99% and stops and looks at one file. Before the new patch i had no problems but ever since yesterday the client is playing up and i can't even get the the login in screen. Ive tried deleting the files in the Lol application, but everything I try from support doesn't work. I even tried to repair the game but it shows the same error. Please does anyone have any advice?
