Hello,
do what GASMASK said if the manual patch is not working,
to make it clearer and expound a bit,
-Download the Auto-Updater tool
HERE
-Follow RESiSTANT's Instructions carefully
-After all files have updated, it will automatically Synchronize when you first clicked the connect button
-Launcher will restart, just click connect button again
- If it does not connect Restart PC
- run InfinityMu
Good Luck
