I'm trying to render something under 500 pieces but the render button is grayed out. When I go to render it the render button is available for about 3 seconds then get's grayed out. When I do manage to click render when it's available the rendering time go's on for hours when it usually takes under a minute. It says I'm online so I don't know what the issue is since I'm pretty sure I have the most updated version and I have default settings. Has this happened to anyone else?
