Here is waht you do:
1 - download and install winhex file name winhex12.2 SR-11.zip
Here
http://files.filefront.com/winhex_wi.../fileinfo.html (by Boulika)
2 - setup your server as you do normally.
3 - run the gameserver, it will bring up a message saying you need user name and password, press ok. you will see that now you have a new window with "Hardeware fingerprint" at the top, username and key fields.
4- DO NOT close this, keep it open, look at the fingerprint, it can be any numbers, for example 4FCC-3A27, you need to switch those numbers around and form a new string. The way to do so is start reading the pairs from the right to the left:
so 4FCC-3A27 = 273ACC4F (ignore the "-")
5 - as I said before, do not close the GS, leave the window open, go to youe winhex and go to tools menu and click on "open ram"
6 - You will see an Icon at the bottm called "Gameserver", click on it and expand.
7 - double click on Gameserver.exe(127 MB), which will open a hex window.
8 - go to the search menu and click on Find hex values CTrl+Alt+F
9 - search for the converted fingerprints (i.e in the example above search for 273ACC4F) find all entries and replace them with 61CC5452
10- after you done so, save, and go back to the GS window that asks for the key and password, put the following
USER: 5254-CC61
Key: 3E3F-576E-FE2B-41FD-B255-1260-31AD-080D-784E-3983
This will unlock your GS =)
DONE =)
