Doesn't work after waking PC from sleep

I have to say that I am really loving Serviio. I use it to stream from my Win 7 64 bit PC to my Samsung TV.
However generally speaking I put my PC to sleep each night or when not using it for a period of time.
On waking the PC, Serviio does not appear on my TV even if the TV is turned on after the PC is wakened.
I have tried stopping and starting Serviio but this makes no difference.
Exiting and restarting Serviio just crashes the program.
The only option to get it working is to reboot the PC.
Any help gratefully appreciated.
