Loosing All Audio Midway Through My Arrangement? Options

[ryanie]

I was working on a project this week and somehow at the same exact point in the arrangement I loose all audio (and all sound from midi tracks) there is no signal on any chanel beyond a certain point. I have no idea what is causing this. The weird thing is it does it on back up and earlier arrangements too... any suggestion to what this could be?

It's a really important track so it's stessing me out quite a lot, any help would be greatly apreciated
