@edward151, it will autoupdate, do not worry about it.
@spartakuss92, it suggests it to avoid any possible injection issues into LOL, but you can always ignore that msg and press NO/CANCEL.
@yetismashx3, yes it works, and it is *kind of legal* because there are other 3rd party tools like lol replay or others, which riot doesn't mind being out there. Also this tool has been working for 10~ months now and no bans reported.
@disenyostig, clear your cookies/cache, see if it helps.
@h0r4ex, няма защо. ;)
@Mikepwnz, XZR APP shuts down or LOL itself?
