Post Processing Graphics Error

Hello

I tried to create a pressure contour after solving the 2D flow over an airfoil and while it produced an unfilled pressure contour, that is to say the colour was only on the mesh, when I tried to create a filled contour I was presented with the error :

Error: cx=set-color-ramp: must be called before start-frame
Error: Object: ()

After this occurs fluent continues to give me this message no matter what type of graphic I try to create.

Does anyone know why this is occurring? Any help that you could provide would be great. I've only found one other thread on this that did not manage to resolve the issue.

I have problems in general with graphics in 2D. It's very buggy and crashes easily. I have to restart Fluent frequently. The more changes I try to make to a plot, the more likely it is to freeze up and throw an error. I'm interested in a fix if anyone knows the cause. It may be related to a specific way that Fluent is setup, linux vs windows, etc.
