When I wrote the Bikki fix, I made it so that it would only work if you had already stopped the Drang/Sturm war. If it doesn't work, you probably have not finished this quest. For a quick check, if Forrad Darre is still in your party, you aren't ready for the next phase. To end the war, visit each jarl to talk treaty, visit Kira to write treaty, wait a while inside Thronheim until Kira gives you the treaty, visit each jarl again to present the treaty, return to Kira where they'll sign the treaty and Forrad will leave your party. Then, Ysra will appear.
Again, if all this is done, contact me and I'll fix you up.
