i had the same problem with the control panel. on the second or third page someone (i forget who) had posted the entire hack in their msg, and it had some stuff they had added, including -at the end- one line that edited my radio or something like that. cpanel uses ubb_lib2 to create the radio buttons it uses, and that line was bad, thats why the radio buttons all dissapeared in the control panel, take that line (with radio in it) out, or just intall from the current file mastermind has up and it will be fine.
