I logged on to the server multiple times and there are no words. Instead of words there are just a bunch of like lines and stuff. The texture pack is working fine but the font isn't i guess?????
I am glad you found your way to the forums as this is a very tricky issue to explain in-game whilst you have these issues. You need to go to your language settings and ensure that it says "Force Unicode Font: OFF" for it to work properly. Please let us know if you have any other questions or concerns.
