i don't know what wedding dash it but still.
1) Are you sure that the program was legit, meaning not spyware or something like that?
2) Try deleting the folder from c:\programfiles\weddingdash (or something simular)
3) scan with antivirus and antispyware program
4) download an uninstaller from download.com and use it to delete the software.
5) it might be wise to go back to the torrent website page you downloaded the torrent from and check if there are any comments, they could help.
6) the program could have another name in the add/remove (unlikely)
