Motu Users look here, help needed !

[Infra]

I have a problem here, I running A Ultralite mk1.
I´ve been using it to my tower-pc for about 2 years, no problems.

2 weeks ago I bought a laptop, installed the drivers properly,
bought a expresscard-firewire-interface, with T.I.-chipset.
However, no sound will come out, and in CueMix The output is disabled = NO SOUND and i cant, change it.
All faders are in the bottom. When I tried to raise the the faders, they automatically bounce back in a second.
Same goes for the output, tryin to change output to (for eaxample) Main outs its setting back to disabled in a second.

I´ve tried diffrent OS, XP, XP64, Vista 32bit and 64, same results.
I tried latest drivers and previous drivers...
I´ve disabled the internal soundcard.
reinstalled the drivers for the fw-interface.

I talked with the Motu-support, And we didn´t get anywhere.
Mostly he just checked the fw-interface, set the UL to factory default...
And re-installed the latest drivers...again. it didn´t work

It still works flawless with on Tower-PC so I´dont think its the Ultralite itself.

Any thoughts about this ? I´m so frustrated !

hardware/computer-related ?

Please HELP ! what can i do to solve it ?
