Maybe it's just me, but I've never been able to get ADB working over wifi with this device. I've had no issues the the USB cord, though. Did you bust your micro USB port?
Regarding the AC app, I know that they were having some issues with syncing the site's new style to Tapatalk, upon which the AC app is based. If you have automatic updates turned on, an update may have been pushed to rectify this. I have been crack flashing, so I have the latest version already from the Market and cannot test for you.
