AES-DEC controller.vhd modelsim simulation error

[ESCHen99]

controller.vhd at simulation throws range error for:
49 round_constant <= rcon_table((i + 1)*8 - 1 downto 8*i);
'integer range 0 to (2**4) - 1'
So it is going out of range. A simple workaround is to range it from 0 to 10 however I do not know it that is neat.
