PHONIC MKII Helix Board 18 Firewire -> Installtion Drivers won't install

1.)
 
I have windows vista ultimate 64 edition, and am trying my tail off to install these blassed drivers cept I run through the install set up.. and i get to the "Disconnect and reconnect your devices and turn them on" next screen*  so I do.. then I click "Next" and it it just sends me back/re loads the "Disconnect and reconnect your devices and turn them on" Over.. and over.. and Over.. its sooooo frickin Frustrating.. How can I Install the drivers.. if the install program is on **** mode?
 
If anyone has maybe had this problem and knows a way around it.. Id be greatly appreciated..
 
Problem # 2.)
 
Oh one other thing.. back when I "had it installed" I would record some stuff in Sonar 8, the wave files would befull* cept in playback at like 25/30 second intervals the sound would dropped out almost completely for a mere instance, then just up and lively a second there after.. but would keep doing it every 25/30 seconds.. if I started the playback from a second or 2 form where it dropepd out.. it wouldnt do it.. till it got to the 25/30 marker... and when I export it.. the drop outs are still in the mix..
 
 
Thanks everyone...

Sorry to hear of the problems - have you managed to get this sorted as I was looking at buying one of these Phonic firwires - think I shall wait for a while!
