error: cannot find column exerID

[blondsecret]

Hello everyone,
after installing a Strokes 'easylearning' CD-Rom, following dialogue is shown to me:

Microsoft .NET Framework
An unhandled exception has occurred in a component in your application.
Cannot find column exerID.

Now I reallly dont know how to fix that and what that all does mean. Can anyone help me?

Thanks in advance.

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 machine (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:

<configuratio n>
<system.windows .forms jitDebugging="t rue" />
</configuration>

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

That's an issue to take up with the Strokes 'easylearning' people.
