I can't update my phone with the NSU, neither with OTA (I have 35 mb rootfs)

I tried to install the firmware with NSU.
It downloaded 165MB, but when it tries to install, it gives me an error (see screenshot)

I use: Windows XP SP3 (32-Bit)
I already installed the update 1.0.1 a couple days ago

My USB ports are not hubs.... (I installed a lot firmwares on different Nokia phones)

What now?
(I rebooted the N900, also rebooted XP.. no luck )
