So I was editing in videowave and en error popped up which made the preview blank and the play/fast forward, etc. controls stop working. If I try to edit anything it says "'Could not create the renderer object. This might be caused by DirectX 9.0 not being installed or the display adapter not fully supporting DirectX 9.0". and if I try to export the project it says "cannot render graph".
I've tried copying it into a new production and it says there are unrecognizable video files. I've changed the rendering to software and downloaded directx 9 (I already had the latest version). I don't know anything about computers so if it's a complicated fix don't bother explaining.
Also this could all be better if I could go back before my last save if anyone knows how to do that. Thanks.
