Adding some pictures would be helpful. You can post pictures using a photosharing service like Picasa or Photobucket. Just upload your images to one of those services and then copy & paste the image link into any Pool Forum post and your picture will show up.

If the liner is ripped, I doubt you can open the pool with it as I imagine the tear will just get progressively worse until you have a full-blown leak. The wrinkles may or may not go away depending on their location and how the water will put pressure on them. I know you all got hammered this winter (I still have family in NY) so I'm not at all surprised.

Dumb question - could your homeowners insurance possibly be used to pay for a new liner? If it's obvious that the winter storms caused damage, maybe your homeowners policy would cover part or all of a claim? Just a thought, may not be worth the hassle.
