How can i repair a cracked/chipped acrylic painting?

I recently returned from abroad and the day before my flight a good friend gave me a (rather large) acrylic painting on canvas. Unfortunately i had no time to research how to get this home, and as i was already bringing home 2 cats, i felt i had now choice than to take it off the frame and roll it up.

Unfortunely, when i unrolled upon arriving home it had a area where the paint had chipped off and wants to chip more, other areas where it is beginning to peal off and other areas where it is cracked. (This may be because the painting, although dry, was painted a few days before i left and finished the day before).

I don't have a lot of money, and i am afraid to transport the paiting. Does anyone have any suggestions on how I can repair it, or at least prevent further damage. Can i use glue? The painting means a lot to me and its beautiful.
