You remove your CC! Thats the problem. Something is conflicting or corrupt. If you want to know what it is you can just:
- remove your newly downloaded CC
- Divide this content into two sections. Label folders 1 and 2
- Place one section in the Download folder (1)
- Load up the game and see if the corrupt file is in there
- If not.... remove (1) and place (2)
- Chances are the corrupt file is in here. So load the game and be sure
- When the crash happens exit and divide the CC again into (3) and (4)
- Just follow the above steps so until you gradually found the file.
Or you can just remove all the newly downloaded CC and add downloaded files gradually.
