I have created a visual web part called "PredatorAudit". I have deployed it to a SharePoint 2010 server using Visual Studio 2010. The problem is that I can't choose it. It is not under Custom or any of the other groups when I try to insert a new web part on a page. I can see the web part in Central Administration - Solution Management, however. It should be in the Custom group because it says <Property Name="Group" Value="Custom" /> in the elements.xml of the web part.
I can choose all the other visual web parts I have created. What could be the problem?
