Can't access/find module...

[Banagan]

I added a free newsletter popup module. The front end works fine, www.lookinfriday.co

Now I want to edit it, but can't find it in the backend. I assumed it would be in modules, but I can't find it there. 

There's a big list of modules, but not the one I just installed. 

I tried to install again, upload module button, but both the select file link and drag drop feature are not working. 

Is this an issue/bug with prestashop?

Could the zip module I downloaded be corrupt?

Where/how do I find modules I've installed?

Thanks

you can use ftp, open modules, sort by date/time updated.  also if you provide link to new module we could tell you module name.
