Hi,

I'm trying to get Commerce up and running, but when I try to access the Commerce site, I get an ArgumentNullException:

[ArgumentNullException: Value cannot be null.
Parameter name: user]
   Mediachase.Commerce.Customers.Security.CustomerSecurityProvider.CheckPermission(MembershipUser user, String permission, Object securityObj) +209
   Mediachase.Commerce.Security.SecurityContext.CheckPermissionForCurentUser(String permission, Boolean throwException) +120
   ASP.global_asax.Application_AuthorizeRequest(Object sender, EventArgs e) +645
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +136
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +69

What could the cause of this be?
