BIG midi problem with pt10

[Trommelfell1]

I have a BIG problem.
My system is win7 64 bit and Pro tools 10.

Audio works fine but midi crack up my computer.

My audio gear is: digi002 rack, Sonic core creamware.
My midi gear is: digi002 rack, Sonic core creamware and midi express 128 and aturia factory.

Midi input works fine with Digi002 rack, and Aturia factory.
Midi output works fine with Digi002 rack.

Every time when i choose midi in or midi out - midi express or sonic core, there is no signal and the hole damthing hangs up (no bluescreen it hangs completly).

So in Cubase all midi in and out is fine -sonic core, midiexpress, digi002, aturia factory.

and by the way i launch protools as Admin, and all drivers are the latest (64bit driver).

any help??

ps: the midi out of motu midiexpress and sonic core is EMULATED!!

my english is not so good but i try
