Technical issues with Heroes III.

I looked at the distribution. It's 2 GB, while the original disc was 700 MB. I'll send you a link to the "Complete Collection" version that I play in a private message. It only differs from the original in that it has a built-in NoCD patch (after installation, the game doesn't require a disc). Install it, apply the HD mod, the Russian super-pack, and SOD_SP (if you want more comfort), configure it, and you're good to go.
