Although this shouldn't be the issue, I would recommend disconnecting Deepbot from your Twitch account for the moment. Don't worry it will reconnect with it once you have managed to get past the login screen but I'm just wondering if this is preventing you from obtaining a new oAuth password.
Log in to your Twitch account and go to the following link
http://www.twitch.tv/settings/connections. Find Deepbot in the list that is near the bottom of the page and hit disconnect. Do the same process with your bot account.
After this try and log into your bot account on Deepbot. If that doesn't work there are other options which i'll have to trawl the forum forum for but we'll cross that bridge when we come to it.
Hope that works,
