how do you fix a double glazed door that wont open.from inside or out.The top and bottom releases,but the middle wont.

It sounds like the centre mechanism has failed if you are not competent in this field then I suggest using a reputable lock smith or installer (TIP-always ask what the callout charge will be first!), or the door might have dropped and needs the glass re-packing (toe & heeling) which is causing the centre latch to jam.

3 ways of doing this. 1 prise a chisel between the frame and door and pressure it will pulling or pushing the door it should open as the plastic should bend
2 if it does not then remove beads around panel remove panel and try again as above
3 remove hinge cover and unscrew hinges and the door will come away from frame then refit
