Links for wallet binaries aren't working. 
1. it is easier and more secure to compile from github than running the binary.
2. the link to binary on blackcoin.co works fine for me.
Not everyone has the skills to compile a binary so it's impossible for them to use any wallet without a binary.
but the link to the binary is working.. (at least at my end)
edit: also the instruction on compiling/installing is here: http://www.reddit.com/r/blackcoin/wiki/installation-and-building
I know what compiling means, but the problem would be compiling on Windows. I have a Linux machine, but it is very old (9 years, and sometimes resets out of nothing) so compiling something on it would take ages.
