Attachments received as .dat or corrupt format

After installing the new Pro 8 version, when I send emails with PDF, JPG, XLS (Excel) or any other format, the recipients can not open the attachments as PDF, JPG or xls…they just see “filename.dat” format and can not open the attachments. What’s going on??

Does any one know how to add these file extensions in the Attachments for eMclient v. 8??

Can you send me a test message with an attachment of one of these types that regularly fails for you?
