Problem with EPiServer Languages add-on

Hi

I am setting up a demo site and having some issues with episerver langues add-on. 

Installed new Episerver web site project  "alloy mvc" from Visual studio.  I run the site and enables one extra language and enables new language in edit mode.

Hi,

I think your solution is right to the point.

Root error is show in the log:

[InvalidCastException: Unable to cast object of type 'System.Web.Security.RolePrincipal' to type 'EPiServer.Security.VirtualRolePrincipal'.]
EPiServer.Labs.LanguageManager.Controllers.LanguageStore.IsCurrentUserInAdminRole()
The function IsCurrentUserInAdminRole() try to cast (EPiServer.Security.VirtualRolePrincipal)PrincipalInfo.CurrentPrincipal to determine you are admin (in Administrators, WebAdmins group or not).
We will try to improve it in a more elegant way using System.Security.Principal.IPrincipal, if possible.
Thank you.
T.
