I have been having an issue with my MC 1.7.10 crashing once I load up a new world (heavily modded client, over the past few days I have been going through my entire mod list and removing any mods that gave errors, until i got to a point where i can get to the main menu, which I have done). Even when I create a "Default" world over a "BOP" wold it will still crash and im not sure where to post this so im posting it here. below are the crash logs:

if you need anything else let me know.
Either delete your options text file, or open it in notepad or something and modify the GUI scale value to something possible, such as 0.
