Edited Issue: Stylesheet not found [276]

Hi,
my system is Windows 2008 32bit whith IIS7.
After new installation whith BugNET-1.6.329.0-Install.zip, no css is found.

Probrably the problem is how to configure IIS becouse in first step i have problem with link without .aspx.
Solved with url rewrite:
<rewrite>
<rules>
<rule name="senza aspx">
<!--Removes the .aspx extension for all pages.-->
<match url="(.*)" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="{R:1}.aspx" />
</rule>
</rules>
</rewrite>

In attachment you can foud a screen shoot.

Please help me.
