iO|26 + MacBook = cannot start midi server :(

[60Hz]

This is my first post here so I would like to say HIII

I'm writing this because of a problem that I have with a MB404LL (Macbook 4.1 C2D 2.4) and the Alesis iO26. OS X is the newest, up to date, Leopard, and I use the most recent drivers form alesis.

The audio seems to work fine, but the MIDI doesn't MIDI config utility says that MIDI serever cannot be started.

I've tried reinstalling the drivers, removing midi config file (from /library/Preferences/ByHost), creating a new user account..

Thanks for any hints,
Tom.
