FTP/SSL connection gets 'bad certificate' message

I am running under Windows 7 using a Winscp console session to attempt to connect using my FTP client to a secure server with FTP/SSL thru port 990. I have imported a CA certificate to my trusted store but I am getting a 'bad certificate' message. Below is the entire Winscp log of the communication. Any suggestions you may have are greatly appreciated:

Re: FTP/SSL connection gets 'bad certificate' message

Are you able to connection with any other FTP client? Can you post a log file from it?
Please please upgrade to the latest version of WinSCP

FTP/SSL connection gets 'bad certificate'

Hello,

Yes, I have been able to connect to a secure Filezilla FTP server(ftp.secure-test.com) without a problem.
I also get the same kind of error (certficate not trusted) using another FTP client system called SecureFX attempting to connect to the problem FTP server. My software install admin rights are strictly controlled by our corporate policy.
I will check with our system admin to see if he will upgrade the version of WinSCP we have been provided.
I was hoping there is a way to suppress to server certificate verification process using WinSCP to prove that the problem is with the server certificate and not my client certificate. I have tried using the 'CERTIFICATE' option of the open command to automatically accept the fingerprint of the host server certificate, but I still get the same error.

The owners of the server are checking into the problem on their end but haven't gotten back with me.
As far as I can tell, my client certificate has been install properly. I can see it in the 'Personal', 'Intermdediate' and 'Trusted Root' certificate stores using IE.

Thanks for your help!
