Glyn Hodges expressed his disappointment after Wimbledon again allowed a lead to slip through their fingers.
Following Ryan Longman's 18th minute opener, Accrington found a way back into the game and two goals in four first-half minutes were enough to inflict Wimbledon's first league defeat of the season.
"I am disappointed," said Glyn. "From being 1-0 up and quite in control, we couldn't defend a wide free-kick. We were slow to react to it. Then a few minutes later they hit us on the break and there was no organisation behind the ball, we were very quiet again, and we were hit with a sucker punch. In the second-half I felt we controlled it, we played well and had chances. Shane's effort was a great one that hit the post, I thought it was in. We are disappointed with our end product with all that pressure.
"Another opportunity has gone. Last time here in the league we got pegged back and the same has happened here. That's football as teams cause you problems and we just have to see the games through. I am saying the same things as we are conceding at key times. If we had come in at half-time leading 1-0 we could have organised it and we would have been calm and controlled the game, instead of fighting for our lives."
Our manager brought on Anthony Hartigan and Ethan Chislett in an effort to open up Accrington, the latter coming on for the injured Terell Thomas, but Glyn admitted that his side did not work the keeper enough.
"We changed the shape a bit after Terell came off to try and unlock their defence. Anthony has a great right foot, he can create, and Ethan can score and create, so we were just looking for that edge, or for something to drop for the equaliser. We nearly got it with Shane's shot. We were there or thereabouts, without finding that finishing touch.
"We just need to have a few more things up our sleeve and a few more personalities to take the game by the scruff of the neck, perhaps something different to open up the opposition. That's why we put Ethan on and he was unlucky when the ball got stuck under his feet. We threw lots at them, without really working the keeper enough. I am just really disappointed."
