did u edit the s1,w1, and worlds.dat according to your server name and IP??
if u did not..then you should do that to be able to connect to the database..
To open the s1 and w1 files u need a program called Flash decompiler Trillex then you edit them to the name of your current zero server.. if you need more help try looking at the thread [guide] how to make a private zero server
first edit your world.dat you will need to use a hex editor or very carefully use notepad ++ (you cannot use regular notepad as it will not show null)
you will see that in your world.dat that it refers to the ip address of your server and the w1/s1 etc flash
take note the number which it says here it may not be w1/s1 maybe w1/s2 or another number you can change it if you like as well
okay now copy the server name from your world.dat and put it in to the flash
done this process should take about 5 minutes remember to save copies of your files before you edit them in case u have errors
as a side note I now am able to offer inexpensive server management as well as hosting if you would like some help with your server and arent afraid to pay for it feel free to message me in private
