mac os x lion and cubase 4 issue

Just updated my mac pro to lion because i needed it for some plug-ins. The problem is that i can not make my audiotrack record enable. I get the message that ‘cubase could’t not load record track’. It’s not a problem for midi or instrument tracks. Anyboby has an idea?

The second problem is that in snow leopard halione one does not work ( he doesn’t find the samples). Halione one works perfect in lion!!!
