Offen Ameise: Execption beim Artikelimport

[DirkGru]

Bei jedem Versuch mit der Ameise einen Import mit einer Datei vorzunehmen, welche wie das erste Tutorial aufgebaut ist, erhalte ich die folgende Exception:

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.


Wer kann helfen? Dieses sind meine ersten "Gehversuche" mit JTL.
