unresponsive in Yandex since a few days ago

[Rezo Simon]

Hi, I recently moved to Yandex browser and all chrome extensions just seamlessly migrated - including Session Buddy.

But for the last couple of days I whenever I click on the extension icon it's in vain, it has not been opening since maybe a week or so. I'm afraid of losing the data that I haven't exported yet, a few sessions. Have the latest version installed, just checked in Chrome store a few minutes ago -  3.6.4

Could you help me get any idea why it would be unresponsive, or how to save the remembered sessions that aren't exported yet?

Thank you very much for your great extension,

Kind regards,

Simon
