Well, I'm not a computer expert really, but I can sympathize with your problem! Yesterday, we couldn't get an SM because it said daily limit was exceeded, even after cookie clearing and all, but then today AFTER I did the regular and DH the SM, I noticed that on the regular survey it had the addy we use for the SM. So something got messed up.
But for you, maybe it's just that you did them later last night, and will have to wait for a little later today to try again?!
