I am back to my main pc and I got one update like 300 MB in LOL.Client so I do the update and when I open it I got this message and I dunno why anyone knows how to fix that?

"Maestro" is the riot server. Idk why this happens. Just play safe and reinstall the client and should be fine. if its not. clear anything you can find with ccleaner and should work :D

I installed drivers and java and I clean my system with CCleaner anyway thanks.
