above ground pool problem (replace, walls, England, new)

[brrrinmass]

Anyone have an above ground pool that didn't make it thru the harsh New England winter we had this year. My pool walls buckled a little bit. They do not appear to be rotted (the pool is only about 7 yrs. old). They are just a little wavy on the bottom portion. They are not folded over on themselves. Can I simply replace the liner? Will the walls hold up as is? Any pool owners out there?
All of the structural members appear fine also.
