Problem upgrading with Vista x64

[XL3N7]

I have a PDA2k which I flashed to Rom Version 5.60.00 WWE, with Radio Version 1.12.00.
I am running Windows Vista Ultimate x64 and the Mobile Device Center recognizes my device as a BlueAngel.
When I try to update the drivers of my mobile device, I get the message:
"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.(Code 39)" I have followed the instructions from the wiki and I am trying with the x64 drivers.
I have also tried upgrading, to see what happens and the upgrade utility comes up with the error message: "Error 150: Rom Upgrade Utility Error"
"This ROM upgrade utility does not design for your device. Please get proper ROM upgrade utility and try again"

Has anyone managed to upgrade with Vista x64 or will I have to use XP?

Thanks
George

BTW I have disabled driver signing on Vista

I have the same problem, and is because the Windows x64 don't use unsigned drivers, so the drivers in the wiki are useless; and if you want to upgrade your device, the only option is make it with a Vista x32 or with a XP.
(I didn't find other solution)

I thought that the x64 drivers are ok. Have you tried some other driver source than the wiki?

I have tried the x64 drivers from the wiki and also drivers I found after a search in the forums. I guess if we could find signed drivers it would work but for know, I have used my laptop with Vista Home Premium x32 and after 5-6 minutes it was done.
Thanks for the support guys
