This despite former manager Brian Tinnion quitting the club, and former Latvia boss Gary Johnson arriving from Yeovil Town.
Speaking at the club's AGM, Lansdown said: "I take full responsibility for the League position and the financial state we are in.
"As chairman, I can't hold my head up high and say I've done a good job.
"We need to get into a situation where the football club and the stadium company are, at the very worst, breaking even."
