System.BadImageFormatException - Invalid Token when updating DLL to newest version?
<p>I've had this project running for a couple of months using a couple of company-specific DLL's. I just downloaded and updated to the newest version and I am now receiving this error. I don't believe it is specific to the DLLs themselves, more something in my project not expecting new versions. The stack trace isn't very helpful.</p>

<pre><code>Server Error in '/dashbad' Application.
</code></pre>

<p>Invalid token.</p>
