Serviio not able to access my directories

Hello, I am somewhat green when it comes to this kind of networking. The problem I am having is that I have 2 computers, 1 is the pc I use for everything and the other is just for storage. I have the 2 networked and am able to access/view files on the second computer on my main etc. What I am trying to do now is get a wireless link between my computers and my TV (with Samsung Blu Ray, BD-D5490). I have Serviio installed on my main computer and have added the network paths of the video files etc to Serviio. Serviio shows up on my Blu Ray menu and am able to "log in" but no files are there. I opened the log and got this:

XXXX-PC\Media (E)' is either not an existing directory or cannot be read due to access rights

I added a folder on my main with a video and added the path into Serviio and was able to play. I am assuming that my problem could be 1 of 2 things.

1) Does Serviio need to be installed on both PCs?
2) I have a password on my second PC, how do I get Serviio to access my data on a passworded computer?

Thanks for any insight. I have added the log for reference.

No, Serviio doesn't need to be installed on both machines.

This is an access rights issue - the Serviio service needs to be given access to the network path. Search the forum, plenty of advice on this. For starters see the wiki and this post from stupid_productions.
