Examining the images section, to pick one, sees attachments working for this one. if attachments are working for one person then the issue is on your end and not the server end. Tell me, have you attempted to clear your internet browser cache? Perhaps it is still associating the attachment processor with the problems from before. If you do not know how to clear your cache please tell me what browser you use and I can get you a walk-through. A quick test, if you like, is to hit F5 when viewing the attachment.
