I know you closed this - but for future reference you and others - your web.config has a debug level output parameter - set it to debug. Your SQL query will be logged in order to provide some very useful info.
I have used the query generated in the log to troubleshoot what appears to be incorrect or missing ..
From Web Config find or add this

<configuration>
  <appSettings>

<add key="Logging" value="{  File: '~\\App_Data\\Log\\App_{0}_{1}.log',  FlushTimeout: 0,  Level: 'Debug' }" />

     <appSettings>
<configuration>
