Boot hangs at md0.uzip

[Frotty]

Hi,

I have been unsuccessfully trying to boot pfsense for 2 hours now.
I tried different hardware, memory sticks, usb-ports etc.
The machine I want to install pfsense on is currently running IPFire fine, but when booting from usb-stick (with option 3) it always stops at

md0.uzip: xxxx x xxxxx blocks
```(idk the correct block numbers)

It's just like this thread http://forum.pfsense.org/index.php/topic,55217.msg295256.html#msg295256
But the solutions there didn't do anything.
Pressing CTRL+T doesn't do anything at any time during boot.
I've waited ~20 minutes on the different machines etc. nothing happens.

I'm really stranded here. I have no idea why this happens and the only Thread I want is the one I linked above.
Any help would be appreciated…
