A Lee Molyneux hat-trick gave bottom side Accrington a crucial 3-2 win over fellow strugglers Barnet.
Molyneux put Stanley 3-0 up at half-time before Elliot Johnson and Ross Jenkins gave Barnet hope but they could not find an equaliser, and the late dismissal of player-manager Edgar Davids made the Bees' afternoon even worse.
The result left both sides on 40 points, with Aldershot joining Accrington in the bottom two after Jack Midson scored the only goal to hand Wimbledon the points at the EBB Stadium.
Plymouth also sit on the 40-point mark following a 2-1 home win over 10-man Fleetwood.

David Ball pulled one back for Fleetwood, who had Paul McKenna sent off late on.
Torquay are the fifth and final side on 40 points after coming from behind to take a draw against Southend.
Freddy Eastwood opened the scoring for Southend but Joss Labadie levelled in first-half stoppage time to secure a point for Martin Ling's side.
Table-toppers Gillingham saw their lead cut to four points after being held to a 1-1 draw at Morecambe.
Jack Redshaw gave the hosts the lead before Bradley Dack levelled for the Gills shortly after the interval.
Port Vale took advantage of Gillingham's draw, moving into second place and closing the gap to the leaders courtesy of a 2-0 win at York.
Neither side has been in great form but goals from Jennison Myrie-Williams and Lee Hughes gave Vale the points and means York have now gone 14 games without a win.
Burton had been second before the day's fixtures but they could only draw 1-1 at Dagenham and Redbridge.
