Actually, I did download it from the source, it just seems that the source download hasn't be updated. Reportedly though the mod IS up-to-date.

I am 99.99% sure that all of them are up-to-date. Every mod I grabbed had a 1.7.2 version (though to be fair it's possible I might've accidentally downloaded the 1.6.4 version). But I'll take a quick look. EDIT: Okay, looks like you were right. Stuff Worth Throwing wasn't actually up-to-date (despite being labeled that way). Removed it, game runs fine now. And next time I'll pay more attention. :\

No, actually, that's the version number for BiblioCraft. 1.6.3 is for 1.7.2. (I just checked.) There is no version of BiblioCraft for 1.6.3, given 1.6.3 wasn't actually publicly released (excluding snapshots; in stable releases they jumped from 1.6.2 to 1.6.4). (Even if it was BiblioCraft for 1.6, it'd throw a different error.)

So, I just finished getting my 1.7.2 configuration of mods set up, and upon launching I got a rather strange error (at least from what I've seen). I've already looked around, I haven't found anything on this particular error, so I figured I'd ask about it here. I have the logs here and here. As of right now, I'm using 22 different mods (not counting core/utils mods, which are installed): - Doom-like Dungeons - Slime Dungeons - ChickenShed - Extended Workbench - Deconstruction Table - Archimedes Ships - Backpacks (Brad16480's version) - BetterChests - BiblioCraft - Botania - Chisel - Extra Uses - Flan's Mod (no content packs installed, currently) - MedicCraft - MineChess - OresPlus - Stuff Worth Throwing - Reciper - Sweet Tea! - Thaumcraft 4 - Village Taverns - Warp Book All of these can be found through this page fairly easily. (I also previously had AE2 and Extra Cells 2 installed, but removed them to see if they were the cause; they weren't.)
