Whenever I launch Tequila I get this error message:
Manifest download error for http://patch.savecoh.com/manifest.xml
An exception occurred during a WebClient request.
When I try to re-validate the manifest I get:
Access to the path 'C:\Games\City of Heroes\tequilalog.xml' is denied
I've tried deleting the files like you suggested, but whenever I run Tequila it just redownloads them and gets stuck on "Finding manifest"
