Well, like you told me in-game, you don't really understand what we are talking about

.
You managed to download and unzip the mapmaker package, so at least you understand that much about computers!
First step is to find the folder called 'server' where you unzipped the package (it should be there with a load of other folders like 'client', 'editor', 'maps' and so on).
I have put a zipped-up version of daimonin_server.exe
here for you to download and try to see if that fixes your problems - just unzip it into the 'server' folder to replace the existing daimonin_server.exe that you have.
If it works, you will see a command window, with the last line saying "Waiting for connections". You can then run your client and connect to 127.0.0.1.
If the server still doesn't work, look for a file called logfile.log in the 'server' folder. Post that here - open it in Wordpad (NOT Notepad, because the file has funny line endings and Notepad can't cope), then select everything with control/a, then control/c to copy and then control/v to paste into the reply window.
Then we can get some idea what is happening.
