Re: Please help....can't attach anything
Use super glue to attach them. ;) easy way.
For attachment I think you have to install their plugin that appear itself when you try to attach for the first time from a fresh installed windows.
If it is not working then see if you are getting a small bar under the address navigation menu asking you to allow the installation.
If you already have installed it then try to be more specific as which browser you are using. and what OS you have.
About the non authentic problem, it can be discussed on this forum according to the rules and regulations of the forum.
