From Pro to Lite

Hi all,
I always used ICQ Pro since 2001 but now it became too big and a lot of advanced features are useless… but the main advantage of lite is that it’s totally localized in a lot of languages so I prefer to use it…
Just few questions:

– What will I loose using lite instead of pro (I mean important features)?

– Anyone can explain me how to activate message logging in lite version (I think it’s te big missing feature of lite)? I red past message about it but suggested link doesn’t work.

– Will I loose my message archives and contact list stored in 2003 subfolder (I’m using 3916 Pro build)? Any way to save them?

Thanks all

P.S.
Will there be full localized pro versions (like lite ones) in future?
