u are sure u can move in your walker, i dont think so

Look at your Login/Logout buttons and then move now u should see it.
what a protocol u use, i use 486 and ip 24.225.249.79, cuz this is not a real C3 server its an C2 L2j but with compatibily for C2 and C3 client
btw u can use 530 and 486 but i still get an logout when ill move, thats weird but i had this problem on some other L2j C2 servers, hmm...
edit: i can try all (emotics, write in chat, use shop and npcs etc.) but when i click on the virtual map and try to move then the walker logs out. Ive seen some ppl on GameHaqs have the same problem with L2j C2 servers and they didnt found any solution atm :S
