AB 4.1 crashes in max 2015 while rendering (max 2013 ok!)

[bewegt]

hi ,
in max 2015 sp3 with aburn 4.1.4 ( fume 3.55 ) max crashes all the time
while rendering.(preparing lights....=) . switching lights OFF was not
helpful. i've been trying the same rendering with a few different scene setups.
same crash while rendering.

do you have a working AB.version/workaround for 2015, since in 2013 everything is
rendering as it should.
the file setup has formerly been done in 2009.
thanks in advance.
