problem with live's time limitation when rendering

[yogz]

Hi,

I have an issue with the rendering in ableton live (7).
when I want to rendered a radio show I've recorded (about 3h30 long) , I get this message from live :

"The selected time range is too long to be rendered into a single file. 2163 MB would be requiered for each rendered audio file, and Live only supports rendering files of less than 2047 MB"

my first quesion is ,
is there something that can be change in live so the rendering could work? (I've tryed to edit in the preference, like sample rate... didn't work)
and the second one,
if I can't manage to do that in live, does anyone know a soft that would do the trick (meaning render 2 files , then consolidate in one)

thanks !
