Liner making me NUTS!!

We installed a new AG liner two years ago in the spring. It was a great summer. THEN, winter came, and we realized it leaked (almost completely empty). I called the company, and they said they would replace if tear is in a seam. Needless to say, I couldn't find the leak. Now, after winterized for months, the pool is empty..again, and the liner is pulling away from the wall. PLUS, my new pool cover has torn to shreds because there was no water in the pool to help keep it up. Sheesh!! I am ready to give up. Any suggestions? I really like my pool but am almost finished. My hubby doesn't like the pool or anything that has to do with it (labor). Help! Give me some ideas what to do. It is currently 18 degrees outside, and there is snow and ice on the way tomorrow, so I'm kind of limited.
