Well, I'll take a look at your save, and if it can't be fixed, I'll upload a save with choices close to the ones you've made
EDIT: Yea, your save won't even load for me, so I don't think I can fix it.
Here is a link to a save from the Ice Plains, though it's from a Neutral Path, with only partially siding with the elves, if you wish to fight the last boss:

And here's a save you can import to TW2, should have about the same choices that you've made, you can also use it to view the correct Epilogue in TW1 after the game ends, as the save above will result in a different one:
