Bilingual [En/Ar] CSS Problems

Guys, I'm having problems with my Bi-Lingual website!
I'm using English/Arabic languages, and when I shift to Arabic, text alignment isn't changed (no RTL no Align:Right;)
How to activate the RTL.CSS when active lang is Ar?

Maybe language pack you got does not contain proper value to tell it is rtl language?

It's correctly packed .. I even tried it with many other template installations, and it's working fine!

BTW ..
I'm on HotHotel

send link so we could check

I'm testing on localhost!
I'm attaching a screenshot so you can see the ending (.) is aligned to the right (should be on the other side) + text is aligned LEFT!
