PVRX2 unhandled exception?

[eipnvn]

I've installed the software as a client (in Vista if it matters) and everything was working wonderfully for a few days, then one day I get an error that reads "Unhandled exception has occurred in a component in your application." and the reason it gives is "object reference not set to an instance of an object." I've uninstalled and reinstalled, changed all kinds of settings, but I can't seem to get rid of this. It leaves me with a frozen system and I have to end the program to get out. I was using 10105 so I upgraded to 10209 - still no luck. Any ideas? The full error if you follow it through reads like this:
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.


Sorry for the annoyingly long post, but that stuff means nothing to me... So i wasn't sure what to include...
Thanks!

Does this error happen right as you are starting up the client?

I had this problem, it was because I couldn't access the gbpvr share for the database after a reboot, i needed to log on to the share first.

Yep, that was it, I couldn't connect to the gbpvr directory, it wasn't shared properly - weird that it just now started having problems, but it's fixed now. Thanks for the help!
