Different currency in order / order emails not sent

[greenbox]

Hi, i have problem with VM 2.0.24
This problem is very strange. When customer place an order everything looks good. Currencies and shipping methods are in proper language (set in the configuration). But when the same user logins in to the shop, and display orders - they are in different currency ? different than shop location and customer address ? 

Other strange problem is that Order confirmation email is not sent but user registration email are sent correctly   

Any ideas?

many thanks,
Martin
