Your English is fine matey - don't worry.
I really don't know how to solve your problem - your specs look fine to me. I assume that you've tried moving the graphics settings sliders down to the minimum setting?
If you have then I can only reccomend that you contact Ubisoft support and see if they can help you.
Judging by the lack of replies to your thread I can only assume that no-one else has had this problem.
I wish you all the best matey and I hope you get it solved soon, oh and welcome to Subsim
