Help Me Solve This!

It wasn't hard at all, for me, to find an interpersonal conflict to write about. There has been an incident that has been weighing heavily on my mind recently and I think that it would be a great opportunity to gather some suggestions as to how one should go about resolving such a conflict. I think that this is a situation in which many will sooner or later find themselves in, although it might not be in such a setting or to such exaggerated proportions. So, it will be very useful for everyone to pull a couple of suggestions together.

I have a friend who is the President of some CCA in a particular university in Singapore. One night, I received an sms from her telling me that she has been crying every night and she was afraid that she might fall into depression if this kept up. So I called her to try to console her. When I got her on her phone, she was crying hysterically and was hiccupping in between words. This was what she told me, in brief:

Three nights ago, she was in her CCA studio when she saw a group of people in a heated discussion. She went over to try to mediate. They told her that the event her CCA was supposed to be rolling out the very next day was still not completed. This event was not headed by her, but by her Vice-President, who has never taken a liking to her. However, as they were unable to contact the Vice President at that time, my friend decided to step in and lend them a helping hand.

When they were finally able to contact the Vice President, the Vice President became monosyllabic and cold when she learnt that my friend stepped in to help. My friend mentioned that she wanted to explain things to the Vice President but was never given the opportunity to because the Vice President kept ignoring her.
They still have a couple of months in office before handing over to the new committee and my friend says that she doesn’t want to leave things in such a bad state. She says that their relationship now is worse than before (and it was never good to begin with).

How should my friend go about repairing this broken relationship so that their committee can work well before the hand-over?
