Maybe try opening the Mobile ID app and selecting the "My ID"-ID?
I mean, you aren't using one of the downloaded ID packages (like "Essentials," for example), right?
After selecting the "My ID"-ID, try clicking on the "Manage ID Packs"-button and removing/deleting any ID packs you may have downloaded.
Maybe try clearing data for the Mobile ID app in Settings>Applications>Manage Applications>All
Also, which launcher are you trying to use?
May I suggest you try Holo Launcher?
