I played CoH on my iMac (running 10.11.6) in Safe Mode for several hours last night; no problems. Tonight I go to play online with a friend, the game tells me I need to update to the latest version (which I did last night). But okay, maybe there's a new patch or something. I re-scan, the game downloads again, I go to start it and I get this message: "Error. Can not (sic) find NCLauncher! Please locate the application, run it, and try this shortcut again."
First I try relaunching the game in Safe Mode; I am told I need to update the game. I try to launch in regular Homecoming mode; I need to update. I download all the files again, STILL need to update. I double-check my manifest; it's current. I go to Reset Path; NCLauncher is in my Applications list. I select and save, but when I launch the game in Homecoming or Safe Mode, it still tells me to update.
I finally do as the error message instructed and launch the NCLauncher, which takes me to the old NCSoft website. Close out of that, launch the game, and I go back to the website time and time again. I guess I'll download everything YET again. All evening of this and I didn't get to play with my friend. I'm attaching images of the messages and Island Rum window.
