Hi thunderstrike,
while I feel with you (it's really a shame if you are looking for one of your old favorite games and discover that the media has become unusable for some reason or the other), this is unfortunately still no justification for downloading the game.
If you own a bike, but it gets broken beyond repair -- then that does not mean you may go to the shop and pick up a new one as a free replacement (unless there happens to be a real good support guarantee on it). If you do it anyway, it's called shop lifting.
Likewise, if your media becomes destroyed beyond repair, it's annoying, but it still does not entitle you to download the game from the net. It's called software piracy by some people.
Now one can argue about physical vs. non-physical (i.e. data) property etc. etc. -- but in the end, it doesn't matter -- our forum, our rules, no arguing this point. For various reasons (explained in our FAQ and see also forum rule #0), we can
not tolerate this in any form here. In particular we can not give any support to users who downloaded their games from the internet. Period. Attempts to try to do so anyway violate our forum rules and can thus draw various negative consequences.
So, tough luck, but I suggest you take a look at ebay, or maybe even some game shops -- it's quite easy to get a cheap new copy of CoMI, and so you should be able to play it again very soon anyway
