MaxMsp 4.6.2 error: can't fragload adc~(missing <adc>.....)

    Nov 03 2006 | 1:49 pm
    I've just installed MaxMsp 4.6.2 When I try to open an old patch I get the error message: error:can't fragload adc~(missing sys_getch>), err -2807 When I replace the adc-object with a new one and try to save the patch Max crashes. The whole Audio seems not to work
    I'am using Mac OS 4.7 on a PPC G 4 Alu Powerbook and an RME Fireface 400 Soundcard With MaxMsp 4.5.7 everything works fine...
    Thanks for a hint,
