Load Problems

Hello I've been trying to create a video using fsrecorder, featuring the 737ngx. However whenever I start the recording(after navigating the recording menus) the game does not re-load properly. Instead it will only load half of the cockpit, sometimes the plane is invisible, sometimes building and scenery textures are missing, and sometimes it's just a black screen!Note: this also happens occaisonaly on just loading the flight straight from the free flight menu.Thank you all for any help so much, i'm really stuck here.
