I use HD packs all the time.
Doesn't work.
Lol, I can't even find that one.
I have 15?? MB of ram, and I allocated 1024 to MC.
What version of minecraft are you running?
I use mc patcher. Download it, Set it to HD textures and you should be good. it is extreamly useful for easy mod adds and what not! I'll presume magiclauncher is like it.
They are, I can connect fine except for the TP, and he can use the TP on his side.
1.2.5
Magiclauncher is not like it, and I use optifine, so no.
It's clean.
Clean or not, delete it still. It may have been corrupted by a bad exit, which is what happened to mine. I've been using MagicLauncher since I discovered it and have had this problem at least twice due to texture pack fails. As Nike say, just do it (tm)
