For 300 sq/ft, I wouldn't risk it. It will never look right.
Thanks for your reply. According to the instructions, which we should have read, they say to cut 3/8" off of each end because the boards are not perfectly flat. I was wondering since they have been down that long, should I bother with that?Trex boards come with rounded edges. What do you mean by "cleaning up the edges"? Sanding and rounding the butt ends? Typically you would run a rim board to cover the boards' butt ends and form a finished deck edge.
After you remove your boards, I would take the most-warped one and try to screw it back before buying new boards. If the new screws remove the warp, there is no practical reason why not to reuse them.

As PCD said, squaring off the ends is a deck building thing. It is not particular to Trex decking. The lack of squaring off the ends is not why your decking is giving you problems. It is probably the lack of gaps in the original install.That is called "squaring off the ends." Typically you would let those rough-cut ends run a bit long, and then cut them all at once with the boards in place; squaring the ends and having all the ends line up in the same cut.
