Cannot Open Soulseek

when i click on the icon to open my soulseek client, nothing happens. so i tried a few things: first, i tried uninstalling it and then reinstalling it and that didnt work. i also tried turning of my windows firewall, and that didnt help either. then something else interesting happened, i came here and my login info didnt work! it didnt recognize any of my emails or my username. so i created a "new" account. but still nothing. When i click on the icon it stays highlighted for a moment as if it is going to open, but then nothing happens and it "un" highlights. please help!! I am using win 8.1, and the latest soulseek qt. also something else interesting happened, when i went to install soulseek, the "soulseekqt setup: installation options" window comes up, i click "next", then "install" and i get an error message saying "error opening file for writing: c:\program files (x86)\soulseekqt\soulseekqt.exe click abort to stop the installation, retry to try again, or ignore and skip this file".
