How to fix that annoying NS Error

[zulu1226]

"this server allows players with unmodified content blahblahblahblahblah"
Ok the offical fix to this with 100% no fail also fixes BFHQ Crash
-Complety Uninstall BF2142 and that means regedit and the whole 9 yards.
-Install BF2142
Download and install patch 1.25
-Download and install Northern Strike <you can now download this though fileplanet since EA Downloader is ghey but as long as you have NS purchased on ur email for EA that you use for login it should work >
-Download and install patch 1.4
-Download and install patch 1.5
Run BF2142 and no more BFHQ crashes or that error message when you join a NS Server(s) <since for some reason i only see that 1 NS Server still exists lol or just my imagination.>

Option 2 if your to lazy to uninstall
Go to Run
Type in Regedit and enter
Go to local machine->software->Electronic Arts->Battlefield 2142 and you should see a version numer somewhere of 1.50 change it to 1.00 and repeat the steps above.
This also seem to work for my friend.
