Help with UV mapping problem

I’ve been having this problem when uv mapping, whenever I try to export the uv map so I can edit it in another program like Gimp, it gives me this error message to check console, and the picture attatchment shows what the console says, but I don’t understand what is wrong. If you can help, that would be great.[](file:///C:/Documents%20and%20Settings/HP_Administrator/Desktop/Problem.bmp)
