So I put in what should be the correct command line:
<pre class="ip-ubbcode-code-pre">"C

Program Files\Sports Interactive\Worldwide Soccer Manager 2006\wsm.exe"--database_location=experimental</pre>
But Windows XP tells me it doesn't work. I put the code into the target area under the properties menu like it says in the link you gave me.
Also, I did put the database in C

Documents and Settings\<username>\My Documents\Sports Interactive\Worldwide Soccer Manager 2006\db\ like the link said as well. Did I do something wrong here?
