Hi, I am very new to Concrete5. I am starting to build a site today, and downloaded the 'Login' Add-on to my site, but when I play with adding it to my front page, I placed it, accidentally, in two spots. Then I have no way to delete the missplaced 'Login' Add-on near the header. So I deleted the Add-on from my site. Then tried to download it again from Concrete5, however, after the 2nd time download this same Add-on, it doesn't appear in the Block Type list any more. If I search the Add Functionality, I could still see the 'Login' Add-on showned as Installed.

At this point, I don't know how to add this "Login' Add-on to my front page - I thought you need to Add Block then choose the Add-on from the Block Typle list, right? But I simply don't see it there... Is this a bug from Concrete5?(once you delte an Add-on, you can never have it again)? Or, did I misunderstand anything here?

Any experienced one would help?
