Looking to renew my ODU after some time and on the SD store page it has no option to renew. Is this still viable (and cheaper than buying outright again)? Is there a renew time limit, my ODU ran out in late '09? I have a renew button attached to ODU in Impulse, but i'm very wary about using that, since i don't beleive that will do anything since the sale. Am i being blind and not seeing a renew button anywhere? thanks.
