I have a JXD661 with me. Whenever I insert the SD card that I bought along with it, the player gives me an error message that states ''Access SD card error''.

Hi dude utkarsh...
You did not mention what size SD memory card you are using, according to the website below, you can only use up to a 4 GB SD card.
If your using over a 4 GB card then the player will not work properly.
If you are using a 4 GB card or less, try using another card in the machine, it may be a malfunction in the card you bought.
