Had a problem when trying to enter northern strike Maps over the last couple of weeks (after a re-build of my gaming rig) and have finnally found a perminant fix for it, if your having the same problems follow this....
install BF2142
install the 1.25 patch
install Northern Strike
install the 1.25 patch (AGAIN)
install and update latest punkbuster
sorry if this has been said before but after weeks of checking the net i decided to re install the patch and voilla im now playing assult lines again :yahoo:
Lol, you should have just asked.
I could have told you that directly. :)
