FC United had a baptism of fire in the tough world of the UniBond first division.
Lancaster scored on the break, against the run of play in first half stoppage time through Ian Stevens and United spent the second half chasing the game.
Inevitably, the home side again scored from a breakaway with a late effort from Jimmy Love after FC skipper Dave Chadwick had earlier hit the bar from a header.
Jerome Wright got one back straight from kick-off but it was too late and the majority of the 2,257 crowd went home disappointed.
