Billy Kee admitted the Stanley team let themselves and the travelling fans down after their defeat at Exeter on Saturday.
Striker Kee said the Reds didn't hit the high standards that they are used to in one of the biggest games of the season so far with Stanley in third spot and the Grecians in fourth.
Paul Tisdale's side won 2-0 to close the gap on Stanley to a point.
"It was really disappointing," said Kee. "We let ourselves down and the fans who travelled on the day down.
"We don't know why but we know we will put it right in our next game against Swindon.
"It was a massive game for us, we could have gone seven points clear of fourth place, but they were the better team and now all we can do is move on.
"It's the lowest we have been this season but we know we have not hit top form yet and there is still a long way to go in the season so we will pick ourselves up."
Kee admits it's also frustrating that the goals have dried up - the 11-goal striker last scored at the end of October and, in the four league games since, Stanley have found the back of the net twice after being free-scoring earlier in the campaign.
"It is frustrating that I am not scoring and they do seem to have dried up. I am blaming the yellow ball like the gaffer does!" said the frontman.
"But everyone who knows me knows I will score goals. I have got 10 league goals already and it's a busy period over Christmas and I will score, it's not something I am worried about.
"We do know, though, that as a team we need to score more and that's something we are working on."
Due to their FA Cup exit, Stanley don't have a game this weekend but Kee believes it might help.
"Obviously we would love to still be in the FA Cup but this break might do us good. The games have been fast and furious and it will happen again over Christmas.
"What we have to remember is that we are third in the league and I think it will be the games over Christmas which will help to determine where we are in the league."
