Part of the problem is that the absolute very latest revision is updated typically a number of times every day, and by the time a link is posted in the sticky the SVN already has something new.
Also, regarding your Windows system, what version of Windows, and other specific information (hardware, video card, memory, CPU(s), brand/model etc.) is also helpful.
BTW, what security software do you use? Some firewalls and suites need to be trained the first time the game is run to allow input to work (Comodo is one example).
