Pro Tools 10 & Edirol UA-25ex - can't load PT10?!

[hooks4hands]

Recently purchased Pro Tools 10 for use with Edirol UA-25ex usb interface.

System;
Windows 7 Ultimate 64 bit
i7 2600k
8Gb RAM

I went through the usual steps - installed latest W7 64 bit drivers for Edirol, installed PT10 from the dvd, installed instruments, installed latest quicktime, plugged in ilok and opened PT10

After about 10-20 seconds the following error msg appears;

"pro tools hardware is either not installed or in use by another program"

The only option I have is to click ok and PTools quits. If I try the hold N option while starting PT I get to the window where I can choose either PRO TOOLS I/O or the UA-25ex as my device but either option causes PT to quit.

I have tried changing settings in windows sounds to both allow and disallow applications to take exclusive control of my Edirol - same result PT won't load.

I installed ASIO4ALL and Pro Tools will start but I can't switch to my Edirol in Playback Engine menu?

Any help would be great, I wonder if maybe the interface isn't supported even though - and I quote - the Pro Tools 10 info page states;

Or pair Pro Tools with any other audio interface that supports any of the following drivers:

ASIO
Core Audio
MME
Multi-client
WDM
