Maintainance Menu Won't Update

I’m currently on iOS 4.4.4 and would like to stay here, but my XBMC and FlashBlack are acting up.  I get an error message everytime I try to update/remove XMBC or any of the items under the Maintainance menu.  I’d like to remove and reinstall both of those programs if possible without having to re-install my entire iOS.  Is that possible?  Thanks!
