In light of the current crisis and the instabilities it has brought to the financial markets, our payment processor has temporarily halted processing of payments in Russian Rubles. That means that purchases from within the native client and our website are not possible in that currency anymore, and you will receive an error message if you attempt to do so.
We unfortunately have no influence over this as it is, and also do not have an ETA for when payments in Russian Rubles will be possible again through this gateway.
In the meantime, you can still use the mobile clients and Google Play Store or Apple Appstore purchases.
