Like I said erlier badboyuk, the computer couldn't see the device and I didn't get the USB-logo on my N900 either. I tried it on a XP x32, Win7 x32 and Win7 x64 and none of them worked. So I gave up and gave the job to some nokia people
Anyways, hope to have it back in a few day, now that Ovi store is "kinda" open and all...
