ProgMedia module again :/

#1
Hi,
in new version of ProgDVB I have a problem with ProgMedia client. When i change the channel on server (progmedia server module installed), i can see a picture both on a client and server side.
But when i change the channel on client computer, i am not able to see a picture at all, only black screen.
Tried to show a tab "Clients" in ProgMedia server module configuration, where i can see 1 client connected, but after 2 seconds it disappears and unhelded exception error is shown.
What is wrong today?
Win7 x64, ProgDVB x86 6.50.1

Thanks, Jorge
