Pocket Aces and a beginner

Hi All....Another beginner dilema. Hero is UTG. UTG+1 is an absolute
maniac.....he's comes into 70-80 percent of the hands (with a raise regardless
of position or how many have lagged in front)......I was going to leave the table when the blinds got to me again....but then I get dealt A [img]/images/graemlins/spade.gif[/img]
A [img]/images/graemlins/club.gif[/img]......the CO has not even entered a hand since I got to the table (about
15 hands ago)........

Preflop:

Hero raises, UTG+1 3-bets, everyone folds to CO who caps. SB folds, BB
calls, Hero calls, UTG+1 calls.

Flop[ 3 [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/diamond.gif[/img]]
BB bets, Hero raises, UTG+1 calls, CO calls, BB calls

Turn[9 [img]/images/graemlins/spade.gif[/img]]
BB checks, Hero bets, UTG+1 calls, CO raises, everyone calls,

River[4 [img]/images/graemlins/club.gif[/img]}
BB checks, Hero checks, UTG+1`bets, CO raises, BB folds, Hero calls, UTG+1
3-bets, CO caps, Hero folds.

DId I screw up here by calling the first time on the river? I had top pair....
there was no flush possible......

thanks in advance for the critique.....
