Vista Upgrade w/RAID

I'm running an XPS 410 with a RAID 0 setup. I bought this system last
November, so I qualify for the Vista upgrade.

If I go to the Dell Vista Upgrade page, my transaction is still listed as
"In Process".

I'm wondering if it hasn't been mailed yet because of a potential problem
upgrading with a RAID 0 setup.

Is there anyone running an XPS 410 with a RAID 0 setup that has gotten their
Vista Upgrade disc? If so, have you had any problems with the upgrade?

TIA,
Barry
