hi, and welcome to the forums, i dont know all the details but i can say it isnt your fault, there is a problem with the attachments and has been for quite some time, it is being worked on apparently and once fixed it is hoped that most if not all the old attachments (but not the really old ones) will be restored along with the ability to get new ones posted properly.
