Are you playing with a custom/store world? If so, you'll have to create a InstalledWorlds folder and drag it's .world file into the folder to be able to load that save.

ooh yes my saves are in hidden springs. ill try that now

okay so i was finally able to get through a full school day now. does that mean some cc is messing up my game?

You have something causing your peril, yes. Try reintroducing your entire mods folder and see if the crashes start again. If they do, then it's in there. If not then it's something installed through the launcher and you may be hard pressed to figure out what. I'd recommend reinstalling the CC you're really using in the fresh folder if it turns out to be in the launcher rather than trying to needle in a haystack it if you have tons of content in there.

i tried it with my mods and everything worked out fine. i have so much cc it will take forever to find out which one is causing the trouble

If you have any .package-based custom content that you didn't test, use the 50/50 method: test half the files, and if you don't get a crash, add half the rest. If the game crashes again, remove half the files you just added, etc. It shouldn't take too many tests to find one bad file.

For launcher-installed custom content, try Method by Mell on this page:

You can speed up the process a bit by testing the first half of the .dbc files together, as in, instead of removing all but dcdb0.dbc, you leave in dcdb0 through dcdb5 or whatever. If you get another crash, remove dcdb3, 4, and 5; if you don't get another crash, add 6, 7, and 8. Going back and forth, you should be able to isolate the issue to one .dbc file.

It might be easiest, not to mention necessary, to delete that file entirely and reinstall the cc that it contained, but at the very least, you can keep the rest of your cc.
