imported folders in gibberish, and no emails inside

Hi

I have moved from XP to WIN7 and changed outlook express for windows live mail in Hebrew

I have a folder with all my previous folders, some of them have Hebrew names

when I import the folders, only the English named ones pass and the other are imported in gibberish (like 0*&''$%) and all the messages I know should be there are gone.

when I look at the folder holding these files, I can see the Hebrew folders just fine

I have tried coping one Hebrew named folder and giving it an English name- did not work

Please help

Thanks
