Filemaker Host not seeing database file

Good day all,

Issue -

I have created the file Radio.fmp12, stored in the same networked location as my other filemaker files. (See attached 'Filemaker Files.png').

I am however unable to open this file using a script as have previous done with my other files.

When I open the Hosts window, all my other programs are displayed except for Radios.fmp12. (See attached 'Hosts.png')

I attempted to open the file directly via its network path and filemaker alerted me that the file could not be found (See attached 'filepath.png')

Please forgive me if i am missing something but i can open the file directly from the directory so i am baffled as to why the file cannot be found.

Any help would be appreciated as I am somewhat of a beginner with Filemaker.

Thank you in advance

Tom
