Hey shuo_yang, I actually already tried that method, and I get basically the same error message, which says that "This extension cannot be installed because licensing verification failed. The extension with not be installed."
Also, I tried to collect a log for you, but it didn't seem to work. I made a file in TextEdit, renamed it to exmancoreliblog.yes, and put it in the correct folder (though I had to also create a Log folder). No I can't find the ExManCoreLibrary.log you asked for. Where would that be?
