Query: Not what I expected!

First of all I have to say that I love Kitchen-aid.I bought this item just last week and I was very excited to bake in something I didn't have to grease.I baked a cake and followed all the instructions and let the cake cool completely before unmolding it,I was extremely dissapointed to see my cake fall apart and half of it stuck to the mold.I'm going to return it and will never buy another silicone mold from Kitchen-aid.This is the second silicone mold I try,the first one being that infomercial one.I think I'll stick to the old fashion way baking.
