Cubase 6.5.3 32Bit mode OSX 10.8 problem with Instruments

I have a big problem on my laptop Macbook Pro with 8gb ram and SSD Drives. Cubase 6.5.3 does not see any kind of Instruments plugs in on 32bit mode (exept cubase native plugs), no problem on 64bit mode of course but not load the instances of old plugs written in 32bit like Native Instruments Komplete 8.
I’m using OSX 10.8.1 Mountain Lion. I need to use 32bit mode and my old plugs for work or I’ve to back 6.5.1 and os Lion? I’ve already reinstalled cubase 6.5.3 and all the plugs but nothing appened under 32bit mode. It sucks please help me.

Thanks a lot to everyone.
