I have been playing since 4.0 patch release date with no problems. Today I got home from school and tried to launch WoW and it keeps saying "launcher cannot obtain patching information" Does anyone know how to fix this?!
Start wow without the launcher.... see if anything updates.... then run the launcher again... if that fails try the repair tool.
It's just a game.
It gave me a pop-up with some errors but still loaded log-in screen O.o
Try running the launcher as an Administrator.
