Hi,

appears while importing from mijoshop, products are imported correctly, but orders and address not.

Don't know much about that but, I assumed the problem was the default currency of my hikashop which was SAR, saudi arabian riyal. When I changed it to dollar, and tried importing again, it continues to import with no problem but it stopped at "downloadable products" step. with that error below.

Are there any plans to update the mijoshop import thing? soon? or to fix this problem.
thank you
