Merkwürdige Fehler beim Fit (ISE 11.1)

[Läubi .. (laeubi)]

Started : "Fit".
CS: block property: block_name=/HC573/EXPANDED_FlattenFull/HC573/my_latch<6>1 prop_name=TYPE prop_terse=XDM_PROPERTY_STRING "TYPE" "INV"

CS: block property: block_name=/HC573/EXPANDED_FlattenFull/HC573 prop_name=TYPE prop_terse=XDM_PROPERTY_STRING "TYPE" "HC573"


Process "Fit" failed

Irgenwie kann ich überhaupt nicht erkenne was das Problem sein soll, 
Synthese geht ohne Probleme durch, Code:

----------------------------------------------------------------------------------
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;

entity HC573 is
    Port ( addr_in  : in  STD_LOGIC_VECTOR (6 downto 0);
        addr_out : out STD_LOGIC_VECTOR (6 downto 0);
           latch : in  STD_LOGIC
       );
end HC573;

architecture Behavioral of HC573 is
signal my_latch : std_logic_vector(6 downto 0);
begin
  my_latch <= addr_in when latch = '1' else "1010101";
  addr_out <= my_latch;
end Behavioral;

Was für ein Device?
"Cleanup Project Files" schon probiert?

[Läubi .. (laeubi)]

Device ist ein XC9536XL-10.
Cleanup hat (leider) nix gebracht, das Projekt war sowieso 'neu' sprich 
Neuinstallation->Projekt angelegt->Fehler :(

So, habe ISE nochmal neu installiert, da war wohl irgenwas im Argen...
