I've created a central repository for Powershell modules, but I'm having trouble loading one in particular. The [NTFSSecurity](http://gallery.technet.microsoft.com/scriptcenter/1abd77a5-9c0b-4a2b-acef-90dbb2b84e85) module is failing to import with the following message.

```

I'm running Windows Managment Foundation 3.0 Beta, which includes PowerShell 3.0. I have a feeling that the new security measures introduced in .NET 4.0 are playing a part in this, but running `Powershell.exe` with the `-version 2.0` switch doesn't fix anything either. I have modified my **powershell.exe.config** files in both the **system32** and **SysWOW64** folders to the following.

```
<?xml version="1.0"?>
<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0.30319"/>
        <supportedRuntime version="v2.0.50727"/>
    </startup>
    <runtime>
        <loadfromremotesources enabled="true"/>
    </runtime>
</configuration>

```

The files are not "blocked", I've checked each one individually (as well as run `Unblock-File` on the directory). Permissions from the server end are fine, I've verified that I have access to everything. What have I not checked?
