Import Language is not working

Hello Dolphiners.

  I can't import an language on Settings >  Language Setting > Import.
  After I have choose a file to import and clicking on [import]  it gives me Page Not Found.

  This is a second language and I will keep orignal English.
  Does any one have any idea about it?

 note: D7.9

Does any one know if this feature is broke in D 7.9?  

Your lang file imports fine on my site. I thought the thing was broken on my site. Must be the lang file i was trying to import.

Still researching. I will have to continue tomarrow. It's quite late where i am.

hi, I have this problem too, version 7.0.8

after i click "import" button , then after a long time show me this message : "Error
Database query error"...

Does any one know what's that mean ?
