Travel Dictionary ML-11, squares instead of Cyrillic letters

Hi,
i have a trial vers. of ML-11, can't get it works.
I have a squares instead of Cyrillic letters in dictionary - not in translations field. Does not matter what I choose - polish, russian, czech or turkish.
I have installed sildunir.ttf in both windows and windows/fonts directory, russian font in options is "SILDou....." -does not help.
The same problem with German-Russian Dictionary ver. 3.1.49
The same problem with German-Russian Dictionary ver. 2.7.09

English -Russian dictionary ver. 2.7.24 works perfect, with all russ. letters.

Op.Syst. Windows CE 5.0, StrongARM, Samsung ARM920T.
Any ideas?
Thanks.
