The kindle fire was just recently updated and the update removed root from the device, and it broke the Super One Click root method used. Once another root method is found (it may have been already) the developer of Super One Click will most likely update the application to support the Kindle Fire again.
Here is an article from Engadget talking about the update.
Just when you thought it was safe to root your Kindle Fire with a single click, Amazon has clamped down on homebrewing enthusiasts. The company has begun pushing out an update for the $199 tablet that breaks the root, disabling the SuperOneClick utility in the process. If you've rooted your tablet and are still running a version of the Amazon-flavored Gingerbread, you're susceptible to the update any time you're connected to a WiFi network. However, if you've already made the leap to another version of Android, such as CM7, you can bypass this and any future software updates. There are some improvements with 6.2.1 though, as smoother scrolling, password protected WiFi use and the ability to remove recently used items from the home screen carousel are among the upgrades. If you're looking to read up on the issue before taking action, roll up your sleeves and hit the links below.
From that thread, if you modify the hosts file and put the amazon update server to point to localhost (127.0.0.1) you will not receive the update, but If you cannot use Super One Click, it sounds like it is too late for you. You seem to already have the update.
Steps to disable the Kindle Automatic Silent Update:
- Modify /etc/hosts
- Disable OTASilentInstall
Use an app like Titanium Backup and Freeze the OTASilentInstall apk
- Rename OTASilentInstall (Optional)
Another option is to use a tool like RootExplorer and rename OTASilentInstall.apk to OTASilentInstall.bak.
