I'm having a problem  with The  Effority User Directory Module when I upgrade my DNN community site to 5.6.1.  If I remove the app code section for the directory and remove the <add directoryName="effority.UserDirectory" /> from the web.config, the upgrade works fine, but if I leave it in this is what I get:

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. 

Compiler Error Message: BC30561: 'Collections' is ambiguous, imported from the namespaces or types 'DotNetNuke, System'.

Source Error:

Line 70: _Settings = New Generic.Dictionary(Of String, String) Line 71: Line 72: For Each pair As Collections.DictionaryEntry In modSettings Line 73: Line 74: _Settings.Add(Convert.ToString(pair.Key), Convert.ToString(pair.Value))

Source File: E:\inetpub\vhosts\MYSITE.COM\httpdocs\App_Code\effority.UserDirectory\FakeView.vb    Line: 72

Here's the fix for it if anyone's looking for it:

sorry to bump an old thread but this fix fixed the error as per thread starters initial post. But i get an error on the page where the module is placed:

Error: User Directory is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: A column named 'Email' already belongs to this DataTable. ---> System.Data.DuplicateNameException: A column named 'Email' already belongs to this DataTable. at System.Data.DataColumnCollection.RegisterColumnName(String name, DataColumn column, DataTable table) at System.Data.DataColumnCollection.BaseAdd(DataColumn column) at System.Data.DataColumnCollection.AddAt(Int32 index, DataColumn column) at System.Data.DataColumnCollection.Add(String columnName) at effority.UserDirectory.View.GetUserTable(Boolean FromCache) at effority.UserDirectory.View.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

any ideas?
