I've got problems installing Mer on my N800

First I tried the install file link in the Documentation: No reaction
Second I tried easy-Mer: Installed fine but Extras->easy-Mer doesn't work(white screen then standard Maemo)
Third I downloaded the flashable Image: Doesn't work with the Windows flasher, I've got no Linux PC at hand

Could someone help me, please?

Edit: Never mind, I've flashed it through my netbook
