I used it once when I first installed logonstudio didnt use since.  Went to change the screen and got the same error as mentioned above.  Everything else seems to be running okay Ie bootskin and windows blinds.  I am running 64 bit vista dont know if that means anything. I went so far as to turn off the virus scanner and the uac still get the same error.

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.

I went to the stardock website and downloaded logon studio again.  loaded it and it worked fine.  But now when I look in impulse it is registering an update available.

Rightclick on the update and choose "Ignore this update" and you don't need to see it, unless you've checked "Show hidden updates" in the orb menu.
