Hi Radu,
Yes, I solved the payment part, Marrit has been very helpful. Basically, you can't pay from Romania using either credit card or paypal (don;t know why, but I know of many countrymen that are unable to complete the payment - Ultimaker IT department should have a look). Marrit helped by issuing a proforma that I payed directly at the bank without using the Ultimaker website. The downside is that you pay a 25 Euro SWIFT transfer fee which is high in my opinion, maybe Ultimaker will accept bitcoins in the future. Money has been sent and I'm waiting to see if the transaction was successful. MY advice is to get in contact with Marrit, she is very responsive.
(Btw, support answered my 1 week old question yesterday , by that time everything was solved so I don;t know what to respond to them )
