Cannot connect to S3

[24Seven]

When I try to connect to one of my S3 buckets, I'm getting the error "The underlying connection was closed. Could not establish trust relationship for the SSL/TLS secure channel"

Computer: Windows 2008 R2 Standard, 64-bit.
Running 64-bit of BestSync.
I have successfully run regcloud.bat (using "Run As Administrator") and it completed successfully (Assembly exported to ... and the type library was registered successfully).

The bucket name is 34 characters long and contains both a period and a hyphen.

We have confirmed that thi is an issue of Amazon S3 class when check the SSL/TLS certificate, and have fixed the problem. Please download and try version 7.2.01.

I'm still getting the error "The underlying connection was closed. Could not establish a trust relationship for the SSL/TLS secure channel" using 7.2.0.3 64bit.

This seems to be working with 7.2.05.
