Help with Stereo in LE4

[Tofuescape]

I am new to Cubase so this is probably a simple case of me pressing the wrong button or something. I have been mixing a friend's bands song and up till now, all has been going well...Stereo positioning has been working fine. However, after taking a break from mixing for a few days, I find the whole thing is in mono. I can pan from left to right speakers with the main stereo out channel, and the other tracks show higher volumes in the right or left indicators in the mixer, but the overall mix isn't stereo. OIt makes no difference at all if I solo a track and then pan hard left and right...just stays center. Does anyone have any idea what I have done wrong??? Thanks in advance for your help.

I am trying to understand your situation... you said you were able to pan your tracks before, but now when you try it, the track stays right up the center? Thats kind of weird... it don't see why it would have worked before and not now. I have studio 4, I will look at it and see if I know what you might have done.
