Stars 1/2 - AA on 3 flush flop - did i play this wrong?

[JSampras1]

Check 3 bettor was 26% VPIP, 11% PF raise, 1.3 AF, first raiser was 21% VPIP, 9% PF raise, 1.9 AF.

I was thinking maybe i should just dump this on the flop. Best case 1 has a queen and the other has the A [img]/images/graemlins/diamond.gif[/img], but it's likely at least 1 has me beat to raise on that scary flop. I have to dodge a lot of cards even in that case, and there's no card that could fall that would allow me to raise.

If the 4th diamond came, or the flop raiser raised the turn i would have folded, but i ended up calling down. Was that a mistake, or do i have to pay off unless the diamond hits?
