Yes, I was talking about 'ehr' vs. 'EHR' in the XML file. When I made that fix, everything started working.

The admin console clearly shows the problem: you have two EHR modules, one in D:\labkey_trunk\server\customModules and one in D:\labkey_trunk\build\deploy\modules. Delete whichever one is obsolete... I think it's the one in customModules. You should delete all other obsolete modules in there.

Your breakpoint where the error is reported shows the "good module" attempting to register. If you put a breakpoint on the call to ModuleLoader.registerFolderType() at the bottom of FolderTypeResourceLoader you'll be able to monitor every registration, including the "bad module". This probably isn't necessary since the admin console shows where the "bad module" lives.
