I have spent long time to figure out what was the problem and how to solve it, finally i came up with the below:

i have to change the "FormServer.aspx" file located under LAYOUTS folder in 14 hive, and added the line

<SharePoint:FormDigest runat="server"/>

after

<body runat="server" id="PageBody">

Now Attachments are working fine ;)
