Failed to create new bucket Error on Amazon S3

Hello readers, I have a problem that I encountered while I am using CloudBerry Explorer for Amazon S3,
I am posting also the screen shot of the error message.

CloudBerry Explorer for Amazon S3
Failed to create new bucket.
The error message above is new to me, I used CloudBerry Explorer for Amazon S3 for the past months without any problem, before I meet that error, I don't remember making any changes on my computer's settings,
I have seen a lot of articles in the internet but none was exactly the same with what I have, I don't have any idea on how to solve this problem, please share some ideas to my post here, thanks for reading,
Hope to hear from you soon.
