I recently flattened an improperly stored software CD. It was smushed in a box in a paper sleeve and had so much warp it would hit the mechanism. Almost 1/8" warp.

I used 2 pieces of glass out of some picture frames, cleaned them well, and set the glass CD sandwich directly on the oven racks, with no additional weight. I prewarmed for an hour on the lowest setting, then took it up to about 200F for 10 minutes and let it cool down for an hour. It took out some of the warp, and did not hurt the silk screen image.

Since it did not appear to hurt anything, and I knew 200F is not really enough, I repeated the same prewarm procedure and took it to 280F, then a long cool down with the oven door closed.
Huge improvment, almost flat, did not hurt the printing and the software installed fine.
Dave

You can bend them cold also.
By the sound of it that's what happened in the post in the first place, so you'd think so
