Country flags not working

[mazarin07]

Hello!

I just added the Romanian language (including the flag) on my Admin interface, and installed the language pack.
Now, my webshop (as seen by customers) has a Romanian flag on its top, so the user can click on it to see the webshop in Romanian. The user can also choose the US, French and Spanish flags. These latter are installed by default.

My problem is that one can click on any of the other flags, they will not work.

I think that there is an installation glitch, because the error message shows "lang-en, lang-ro etc. folder not found".
Indeed, I have no folders with these names, so it's not a surprise that those country flags do not work.

When I installed for example the Romanian language add-on, I expected that the setup will be automatically done.

No, if I click the Romanian flag, I get the following error message at http://hu-ro.net/Webaruhaz/lang-ro/index.php
"Page not found
The page you are looking for might have been removed,
had its name changed, or is temporarily unavailable. etc."

Is there any hope to solve this problem, or better to uninstall the whole package and try another webshop software?
