Hi Jackmantegazza!
You check folder language/en-GB exists 2 file
en-GB.mod_jfslideshow.ini
en-GB.mod_jfslideshow.sys.ini
And then you check the existence of mod_jfslideshow in modules folder
If not found, your module hasnt been installed successfully yet
If found but got error, you should rename file .htaccess
Or you go to administrator/index.php?option=com_installer
Install into "Upload Package File"
If there's any problem, let send me ftp, user admin information directly to email
