How can I contact Steinberg support from my country, that’s not listed on supported countries? 
You can use this forum (many competent users) or make a post and bring it to the attention of a moderator, however it is not recommended to write directly with a cold-canvas concern.
Otherwise write to info at steinberg dot de and you will get a response
you should try praying for some support which is almost as good as wishing it were so.
