After login at the down load page I click minecraft for windows: minecraft.exe (270kb). I am brought to mine craft news login page. I see a page appear for a moment that shows green loading bar and it says, "minecraft update done loading". Green bar about 1/4 inch from ending and then I am kicked back to the original download page with minecraft.exe. I tried some fixes from the internet. No luck. Best buy geek squad said the computer could run minecraft. AMD athalon 64 processor 3300, 1.81Ghz, 898 MB of RAM, Microsoft XP home edition 2002, graphics card: sis 760. This is a computer I acquired so my younger son could play Minecraft with my older boy. Currently they take turns on the newer computer that plays minecraft just fine.
