Windows .exe Worlds not loading past the building terrain screen

[Jazzify55]

Whenever I load up a world in the Mindcrack or the DW20 packs it stops at the building terrain screen. I fanyone can help please do. Here's the console paste log, at the end of the log there's some kind of error that's where it gets to the building terrain and stops. The log is in the attached files.

Saw you where using a texture pack so it's prob the optifine B6 skrewing everything up. There have been posts on the forum that optifine now has C1 released that does work with mindcrack V8 and dw20 V5
