Don't help people pirate software...
I'm sorry, but if you don't have the disc then it's just bad luck. but we can't just promote people giving away software...
if you still haev the license key, you'll most likely be able to go to the manufacturers and say, Look I was a customer, and now I've lost the disc can I have another copy, and they would likely say yes...
unfortunatly asking people to send to the files on a forum isn't the way that you should go about it.
