Sir,
Everytime I run ProgDVB5 I get this error:
Unhandled exception has occurred in a component in your application.If you clik conjtinue, the application will ignore this error and attempt to continue.
Object referrence not set to an instance of an object.
(Option) Continue
However if I'll contnue, I could run the program and watch TV.(146E KU band)
I'm using Kworld DVB-s 300 U.
So far not experience any other problem. Just run my rig for 2 days yet.
Sorry have no enoug knowlege re computer terms/language.
If possible can explain in laymans terms.

Here are the Details:(as written in the pop up window}

"See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box."

Is it last version of ProgDVB?

yes. Downloaded last Nov. 25, 2007.

ProgDVB version 5.12.02

Prog,
Problem solved.
Reinstalled Progdvb.
I also realigned my dish cause I get the same pop-up error when I switched to another TP, with low signal level.
Also observed, this USB device has lesser gain compaired w/ STB's.
With very low signal she hangs up, then qiuts.
Thanks,
Art

Prog,
I doubt its a hardware issue.
She comes w/ 12v 1.5A pwr supply, I changed it w/ 6v 4a(swtichng).
She's working fine now.
If I increase the supply to 7.5V, I can see the RF indicator blinking when I tune to TP12301(Sat 146 KU).
If set to 5V she runs for a while then hungs up.
Now can I conclude that this unit is deffective?

Well, that's not really looking good...
Something must be wrong, either with the device itself or with the load.

Juergen,
Thanks, I'll try to bring this matter to the manufacturer.
Regards,
Art
