you must have at last once launched wallet !
To get wallet working :
1) go to appdata using %appdata% command in search (win 7 64bit)
2) then go to coinonat folder, Create Text file and drop this info there :
addnode=138.197.159.60:44678
addnode=192.3.196.202:44678
addnode=88.99.191.218:44678
after that SAVE it as coinonat.conf
3) restart your coinonat wallet and it should work !
if wallet gives error, try to install microsoft visual c++ 2010 x86
that helped me and i have win 7 64bit sp1
