CM4 4.0.3 crack..

[digby22]

Hello guys, hope you can help

I'm new to all this [first posting] and not really too technical.
I've downloaded the CM4 Enhancement pack, and 2 different no-cd patches [idx-cm4w.rar and ChampionshipManager4CM4UpdatePatch4.03NoCD.rar] but I don't know what to do next. If I try to open them, I'm faced with an 'open with' box - what do I use, and then, wot next ??

Cheers, Digby
