DVD Video Soft Error ㅠㅠ

Haizz... I've been using a software called 'DVD Video Soft' for basically downloading vids from youtube and converting them into ipod format. But now, it suddenly doesn't work!! On one random day i just download a normal vid and got this message: Access violation at address 10004ECE in module 'DVSITU~ 1.DLL'. I've just made a post on the software's forum... Hopefully, the Keymaster would answer me quickly... Pls... i'm dying without SJ vids ㅠㅠ
