Ah! At last, something I might be able to help with.
I recently came back to Layo useing a GOG version, and yes , GOG will provide you with a CD key if you ask them. Sadly It may take an honest 24 hours for them to respond to your request but they will.
Oh and I'm sure you already know this but just in case, Layo's server address is "xoralayonara.com" for Milstone and xoralayonara.com:5122 for Dregger. My humble advise is AIM FOR MILSTONE!!!
Lastly, There is alot to figure out here and it may seem a bit complicated and perhaps daunting, but there are very good people here and truely, it is worth the effort!
Enjoy!
P.S. I'd like to thank everyone who have been so helpful to me as I have been finding my way here. You have all been so very kind! Thank you!
