Distinct countries not showing up

Hi all,
I’ve done a fresh installation of piwik v0.4 just to test it before implementation into production.
My issue is not business critical but only a small facelift problem, well… when I go to visitors --> locations and providers at the left bottom side the image beside “xx distinct countries” is not showing up (basically it show that the image is not available with a red cross).
I tried 3 main browsers, tried to clear the cache in the browsers and reload the page but nothing helped.
Anyone know how to fix this small issue?
Any help is much apreciated…

Thanks,
Anis
