What verson of Disk Juggler shall I use to copy backuped cd game?

[Mondo]

Hi guys.
I've got three questions for you guys.

I made a copy of backuped cd games by cloneCD. And it works just fine.

However, after I made a copy and during the playing, only one problem, that is, slow booting time (at the begining) but rest of game loading time is normal.

(1) And I was wondering the slow booting time will damage my dreamcast lense.
(Is it true?)

That's why I want to try Disk Juggler instead of CloneCD.

(2) I would like to know what version of Disk Juggler you gusy's using?

(3) I've got Disk Juggler V3.00.736-DTU (trial version), I tried to use it, But I've got some error message something like "illegal parameter...."

I really hope that any of you can answer those questions.

Thanks for your time.
