when i click on steam it says you may only open one copy of steam at a time, i looked it up on steam support and they told all windows vista users make sure games are not Windows Compatibility Mode.
how do i do this?
Ctrl + Alt + Del, Task manager. Press "s" until you see steam, Click "End progress" And start it up.
right click on steam, click properties
a tab named compatibility should be there
click on that and make sure it isn't in compatibility mode
thanks
