Conversion to PDF fails

Hi Guys

I have been trying to convert to PDF and nothing happens!

When i do it remotely ie on RDP connection on server it works 100%, all the Clients have Acrobat Reader, they can all access the path i specified for Attachments, so what else could be the issue? Is there a security setting in Acrobat Reader that needs to be set? i have looked for this but to no avail.

Thanks For The Help
