Well bro i already did what you told me to 1) Disable and uninstalled too but no luck. 2)Already done that but i think that mutlimarriage mod caused some problems. 3)Well i tried waiting more then 48 hours but no luck again 4)I already got the latest one. 5) i did attempt many time but all the time same problem the ceremony never starts. And Yes one more thing bro I loaded a very old save game in which i was never married and never used mutlimarrige mod too and all mod&updates were enable But it worked prefect then So my bet it is got something to do with multi marriage mod.
