Query: this SD adapter does not work with PE MP4/Mp3 player

I bought "Touch Screen 4GB 2.8-Inch TFT MP4/MP3 Movie Music Personal Media Player" + "Sandisk 4GB MicroSDHC Memory Card with SD Adapter (BULK Packaging) " which Amazon recommend. but the SD adapter cannot be inserted into slot of Mdia player! I went to lots store for help. but I was told, this SD adapter is too big to inserted! Money just wasted!!Very bad recommendation! amazon just cheat me again to buy more unused goods!!
