I want to remove my stationary sliding door to replace it with a new one but I could not get it slided to the middle. after removing the door holding bracket, two 90 degree brackets at top and bottom, I still cannot pull it to the middle. is there any more hidden screws somewhere? do I have to remove any part of the frame where it holds the door in place? Please help with instruction. my email address is at the top. I can send a digital picture to show how it looks like. thanks.
