I think almost all seed nodes were turned off when the Spreadcoin team left for other projects, hence the connection problems.  I downloaded the SPR wallet a few weeks ago and it found some connections after a few hours but I have since deleted it so I can't tell you whether things are the same for me now.

Try adding these nodes to your spreadcoin.conf
