Null Referance problem

Hi,

i recently started too get alot off nullreferance problems in my Project and i havent done anything recently New too my Project.

All the null referances says that i have too drop something in the inspector window and i do exactly as it says and when i restart unity, i get the same null referance errors and the stuff i dropped in correct slots are gone again .

Can anyone please help me With this annoying problem?

im using unity 4.5.2

And many off the errors says that something is missing in its slot, and when i check the slot the correct thing is there already, has this happened too anyone else?

The only New thing i have done is upgrading too 4.5.2 but eveything has worked perfectly fine for like 2 weeks now after i did that.

Can you post some screenshots so we see what you see.

Thx for the reply, i was able too fix it With re import the assets that was having problems.
