client v1.5v0 instead of the normal clieznt

Hi all, I recently download a new patch and I get a strange launcher licent v1.5.0. It seems to be an hold client. I log in with the client and it luach me a normal bersion of lol. The problem is that after 3 days I add in game probleme, high ping and at the end I could not connect to a single game. I then uninstall and instal LoL, which was working correctly for one day and I got this old client version again. I start to have in game problem game. This make me think that it is ling with this strange client. I uninstal again and it just work for one day before I have this strange (root client) client. Do someone now something about this issue and the way I can solve the problem. Thanks for all. best. Req
