Presentation Empty

I am running serviio 1.3.1 on an iMac with Maverick. When first installed it worked perfectly then after I added some memory and restarted the machine ( moved some of the USB connections about) serviio would not show any of the presentation folders at all.
I removed and reinstalled but still the same problem.
I installed PS3 to see if it worked and it was fine but it just doesn't have the plugins the serviio does.

Is there something wrong with the path to the presentation folders? Where does serviio store the info in its presentation folders?

Any suggestions would be appreciated.

Thanks.

Does the server start, ie can you see Serviio on the TV at all?

Turned out i had TVmobili running and didn't know it so there was another server already working.
Works fine now.

Thanks all the same.

Peter
