I have done both, also I removed Chrome and re-installed it.Edit: If i'm not mistaken the location of the app data would be in ~/.config/google-chrome/Default/Extensions which did not contain any old files.Second edit: I noticed that on the details page for the app that it accesses data from dontstarve-release.appspot.com. I assume this is where I would connect to when loading the app? When I pointed Chrome to the address it failed webgl initialization.
