DD11 adv. - Error while moving/resizing partition

I get this error http://forum.acronis.com/forum/13675 while I tried to resize and move D: and extend C:.
I tried many ways now but with same result.

The system is a IBM x3500 server with 6 disk in RAID 1E and running Windows 2008 R2.

First I did:
2 operations in one, Shrink D: in the front, ext. C: to the new free space.
= Error

Than I did:
Skrink D: in front
= Error

Than I did:
Shrink D: with windows
= succes

Than I did:
Move/resize D: to the end of disk
= Error

Than I did:
Resize C: and take all Unalloc... space
= Error

So now I trying to do a chkdsk of D: to find any errors and so on. But Does anyone know some thing about the Error from the link?
