hipchat password not retrieved from credential storage

I am trying to use the OSX Hipchat desktop client v 3.3 (193). I have OSX 10.10.3. I have followed the instructions suggested by Hipchat support https://help.hipchat.com/knowledgebase/articles/166483-mac-beta-client-clearing-preferences

Close your HipChat app
Open Keychain Access (search for Keychain Access in Spotlight)
Click the "login" keychain in the top pane of the left sidebar
Click "passwords" in the bottom pane
Search for "hipchat" using the search box in the upper right and remove any     associated entries from the list
Open Terminal (search for Terminal in Spotlight)
At the command prompt, enter the following commands:
defaults delete com.hipchat.HipChat
rm ~/Library/Preferences/com.hipchat.HipChat.plist
rm -rf ~/Library/Caches/com.hipchat.HipChat
rm -rf ~/Library/HipChat
rm -rf ~/Library/Application\ Support/hipchat/

I am still getting this error

I am trying to figure out where on my computer an extra credential to delete must be hiding, or what permissions I have messed up.

I have access through the web interface but I would prefer to use the native app.

I had the same issue and exchanged email with Support. They believe there is a bug in 3.3 involving port settings which will be fixed in the next update which is "due soon." None of the above suggestions worked.

I had to reinstall 3.2.1 and that fixed the problem.
