Windows 7x64 - Kleopatra hangs "loading ...

Hi.

I’ve just installed gpg4win. First the 2.0.4 version and then 2.1.0 beta.
In both cases when I start Kleopatra it hangs with “loading sertificate cache…” message loading 25% CPU.

I use “Windows 7 x64 professional russian” and strongly need to use gpg with Outlook 2007.
Can anybody help, please ?

Thank you
