i buyed a blood,but when i play there are no modified blood

write this when you're in a server:
/dl eman6
/lp 0 eman6
the last one makes the red player look like you

Make sure you activate it.
On the forum find your deactivated and then activate your new blood.

After that
^ this

I think you haven't activated it yet, so try that and when you log in to the game it should dl you automatic. and then you should have the blood .
