If you are playing on PC, get FoV and you can continue with your existing save.
There were too many changes to loot, enemy placement, etc to maintain saved game compatibility in DKS. It would have been nice to at least be able to import your stats, equipment and inventory from a save at the end of D2:ED, but you should be able to get a fair approximation starting a new level 35 character (your equipment you would be likely upgrading again anyway).
