3.0.3 just lost MIDI i/o in Logic Pro 8

[fierlion]

Why is it that I LOVE and HATE my Virus snow? I just figured out why it intermittently made LFO type drones (the presonus faderport's initial midi driver puts out a constant c-2 note!)
Now I get that fixed. Finally I feel like I've got a perfect setup:
Logic Pro 8 with my Kurzweil 250 as master keyboard MIDI with the Snow as my usb-MIDI box.
...That was before I updated to 3.0.3
Today I opened up the project (with a deadline!!)I've been working on for 2 weeks and suddenly I am getting no midi messages.
I checked the snow alone--the MIDI i/o works great. Once I boot up Logic though, the midi doesn't transmit. It cuts off. I checked my general midi settings, my project midi settings--nothing has changed since yesterday except for my update to 3.0.3
Does anybody have a suggestion of how to fixez-vous?
I tried unplugging my virus+ten seconds of holding the tap tempo as I plugged it back in. I checked that my kurzweil is transmitting. My RADIAS/little phatty both have the same effect...or non-effect. So the stoppage is between Logic and the virus. Oh and I rebooted my computer a couple of times.
Help??
