torrents are pretty easy to use actually.
download Azureus which supports torrent downloads aswell and in stall it.
then type in google something like: Paint Shop Pro Torrent Download
Then you have to search for the download link *carefull with russian sites ....* then u download the torrent *not the programm* save the torrent wherever you want and open it.
Azureus will open itself up and starts downloading it from different ppl.
i dunno if paint shop pro is freeware or not. if it is free u could find a direct download somewhere by just searching through the net.
even better would be if u use a proxy to download but i guess for a one time thing it wont be neccessary.
i hope i could help
Edit: why am i so slow >.> damn you vergil xD
