Can you try uploading through a third party FTP solution like FileZilla - The free FTP solution and let us know if you were able to go through?

Hi, yesturday I tried to upload using filezilla, and cant be possible.
I have contated adobe costumer care, and the could not solve the problem.
They told me that could be a certification problem of my host provider.
I have called my host provider and they could not solve the problem.
Anybody really knows what the problem is. So I'm stuck with it.
I have pretty much the same problem using sftp, get the MD5 error msg using Muse but Dreamweaver, winscp and linux scp all work with no problems.
