Battlefield 2142 – Northen Strike Error – server doesn’t allow modified content

After updating to version 1.5 I found that everytime I try connecting to a BF server I am kicked and the error message states (server doesn’t allow modified content).

Follow steps to fix the bug

steps for fixing NS
1. Go to the start menu and select “Run”.
2. In The Box that pops up type “regedit”.
3. This has opened the registry. Don’t ask what it is, because it’s kinda complex.
4. If you need to make a back up select “File” and then the 2nd option named “Export”. Select where you want the backup and then save it.
5. Over on the left is a frame with all the registry “Folders” for lack of a better word. The third(or so) one should be “HKEY_LOCAL_MACHINE”. Next to it , on the left, is a plus sign. Click on it to expand it.
6. Click the plus (+) sign next to “Software”.
7. Click the plus (+) sign next to “Electronic Arts”.
8. Click the plus (+) sign next to “EA GAMES”. Yes, it is in capitals.
9. Click the plus (+) sign next to “Battlefield 2142″.
10. Find the registry key(entry) called Version.
11. Right click on it and select “Modify”.
12. Modify it to 1.10
13. Exit the registry editor.
14. Install the latest official patch.
15. Try to join the server again.

This should fix the problem.
