Web Forms For Marketers Form Designer throws 'Handle Not Found' Error

In Sitecore 7.2, opening FormDesigner gives the following error:

Exception: System.InvalidOperationException
Message: Handle not found.

I think something is wrong with the installation, but comparing the instance with the WFFM install files, I cant see whats missing. Not even sure what Handle Not Found means?

This ultimately came down to the URL. Sitecore was set to inject the language into the URL automatically (This is a setting in the linkManager section of the web config). WFFM really didnt like this. When I changed that setting, everything was fine.

UPDATE

An example patch would be:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
<sitecore>
    <linkManager>
        <providers>
            <add name="sitecore">
                <patch:attribute name="languageEmbedding">never</patch:attribute>                   
            </add>
        </providers>
    </linkManager>
</sitecore>

Are you adding forms from the experience editor? If so are you able to actually add a form to a page? Are there any console errors when you do this?

Could you check for console errors? Have you re-installed web forms for marketeers in Sitecore?
