I recently got a new computer for Christmas. I did have winxp x32, I used Ender's client x32. Worked fine. I got this new computer that runs on Win7 X64. What happens is that I log in and I notice that my character's pictures are missing the brownish backround, Then I go to log in and it's frozen but I can see some objects in the world but no ground texture. I cannot move around at all. I messed around trying out new things to get HnH to work but all with no luck. I've also tried the vanilla version of HnH but it was very laggy and some objects where not there or invisible. So, If someone could help me that would be great.
Edit: Here's a picture of what it looks like when I log in: http://img201.imageshack.us/img201/5204/hnh.png
Everything is completely still like that. Can't move around or anything.
Edit: Vanilla works. So It's Enders that doesn't.
