Okay so basically everything was fine this morning but after I tried installing a resource pack made for Hexxit, which I deleted completely after this, everything went to crap. Whenever I try to join a server in multiplayer, it loads for 2 seconds, giving you a quick glance at your character being stuck half in and half out of a block then immediately goes to a black screen and crashes.
Could it be the server itself? Could it be something corrupted on my end? I don't know. And yes, I have 2GB RAM allocated to it already, which was never a problem. And I'm running the latest Hexxit version. What I tried:
Deleting (player).dat file
Copying Saves folder, deleting .technic, and pasting Saves folder in the new one
Here is the crash report
