If I'm reading him correctly, he deleted all the fox.ini files.
The files are located here:
For steam
Go to C:\Program Files\Steam\SteamApps\common\blacklightretribution \Blacklight Retribution\Live\FoxGame
Non steam
Go to C:\Perfect World Entertainment\BLR\Blacklight Retribution\Live\FoxGame

When you start up the game after deleting these files, you will be prompted with a msg saying the files are nowhere to be found.
And give you the option to restore from backup.

I got all those bug many times......... specially wearied Deaths. I asked that player how did he killed me? he said he I was stunned and was not moving my body parts but my location was changing.......... i had 5 clones at a time so as i was spawned i died 5 times ...... and all those deaths were been counted in score bored ............. my KDR has been worsen due to that bug. And i is not necessary that this bug should happen only 1s in a match. it may continue and happen any time. And sudden Game Shutdown while equipping DATA nodes. this bugs are more common on the New Maps. Reviving Our Clones gives 1 more chance for death...... it becomes so irritating that we have to do Rage quit......... 1 more bug is we cannot press Alt + Tab the game hangs i need to chang songs xD plz Do something (T_T)

Hello, once again

Thanx for you help @slamtoast and @progotbanned, but i'm afraid that the solution was just temporary. I followed your instruction and at first, it worked, but after a few ours the clones started to appear again.

So, i re-downloaded and re-installed the game, but the problem persist.
I formated my hard-disk, and re-installed OS thinking it might be some hidden file in some god forsaked folder, reinstalled the game again, but the problem persist...

So, i think we can conclude that this is not a client side problem. Please fix this!
