Well, I've contacted GOG; I'll see what they say and I'll give you an update when I get a reply.
If you're sure you got the enhanced version *with* your old version, then something must have gone wrong with my account.
Though, I must say, I've searched the internet since then, and with GOG and D:OS, I often see mentioned that it gets 'upgraded' to EE, not that they just place the new version aside it. So I'm still wondering. But if you say you got the two versions, I guess that should be the case for everyone.
