LUKS over FakeRAID; can't open on windows

[silentpanther127]

I have 2 3TB drives in FakeRAID1 (the cheap bios managed RAID), on there is a LUKS container with a single NTFS partition.
It was set up on a Ubuntu and worked fine right from the beginning, until I tried to access it with another Ubuntu installation. The RAID volume was shown with only 802GB, despite the fact that I could open it, I was unable to mount it.
Many, many hours of hadache later I found out that mdadm (driver for the FakeRAID) was missing. With that installed it worked.
Lateron when I tried to access the volume from Windows, by checking the "whole drive option", I always get an error. After some Investigating, I saw that Windows showed the drives to small aswell and I installed Intel Rapid Storage Technology drivers (again?). Now the drives are recognised as a single volume with the right size, but I still can't open it. Windows is sugesting that the partition table is missing and wants to write one.

I was afraid that this would overwrite the LUKS header, so I did not do it. The partition table is inside the LUKS container, right? and therefore is no need for a partition table outside?

Any ideas how to access the data from windows?
