Sigh Lemonade ban appeal

In-game name:Sigh Lemonade
The admin that banned you:Not sure
The map:Not sure
Reason for ban:Not sure
Your side of the story:I was not banned in game, I'm not even sure if I am banned or not. But when I try to connect I get the following:

----------------
- SERVER PROTECTED BY HLDSGUARD 1.4 PRO
- Your IP Sucesfuly Logged and BANNED By HLDSGUARD 1.4 PRO!!!
- web: www.awakelgcc.narod.ru
-----------

Perhaps I simply cannot connect for some reason, other servers (like AOG) work fine. Thanks if you can help though.
