Launchpad freeses / Hangup afer some seconds of use

[citric_acid]

Hi,

does any one has an idea ?

I installed today on my macbook the actual Live 8.1.3 and the actual launchpad drivers.
Also i installed the latest Max runtime. my macbook runs osx 10.04.11 and a NI Audio Kontrol 1.

I used the launchpad since months on my Imac without any problems so i think the LP is fine and i have some knowledge to use the LP in the right way. No USB Hub is used i go directly in my macbook.

I also took the same settings as on my imac for LP.

So here my problem:

I start Live, also the Automap starts up.
I insert a midi instrument and try to play it on the user1 mode .
Some seconds or minutes later the LP will freez ( hang up ) and i cant go in a other mode like Mixer or session etc.

What can be the problem ? Has anyone a tip or a fix ?
