This sounds familiar, but I can't remember what the solution was. Try sending a support ticket to help.ncsoft.com, they likely keep track of stuff like that.

Save Paragon City! Efforts Coordination
When I tried to load the game tonight, the Launcher said there was an update. The download progressed normally, but the install crashed giving the error message "ERROR Loading local XML: /Applications/City of Heroes.app/PS/CityOfHeroes_Main_2300.201206010513.1.0To2310.2012 06160022.1.0/PatchManifest.xml". The launcher then closed.
I tried repairing the installation and got the following error message: "ERROR Loading local XML: /Applications/City of Heroes.app/PS/CityOfHeroes_Main_2310.201206160022.1.0_Repair/PatchManifest.xml"
The launcher then closed.
Any help would be greatly appreciated.
