I upgraded from a (very old) version of Events to version 5.1.5. DNN is version 5.2.3. There was a timeout during the install, but another try installed correctly (at least, there were no errors displayed)

When adding a new event the following error occurs:

DotNetNuke.Services.Exceptions.ModuleLoadException: Parameter count does not match Parameter Value count. ---> System.ArgumentException: Parameter count does not match Parameter Value count. at Microsoft.ApplicationBlocks.Data.SqlHelper.AssignParameterValues(SqlParameter[] commandParameters, Object[] parameterValues) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteReader(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Modules.Events.SqlDataProvider.EventsRecurMasterSave(Int32 RecurMasterID, Int32 ModuleID, Int32 PortalID, String RRULE, DateTime DTSTART, String Duration, DateTime Until, String EventName, String EventDesc, Int32 Importance, String Notify, Boolean Approved, Boolean Signups, Int32 MaxEnrollment, Int32 EnrollRoleID, Double EnrollFee, String EnrollType, String PayPalAccount, Boolean DetailPage, Boolean DetailNewWin, String DetailURL, String ImageURL, String ImageType, Int32 ImageWidth, Int32 ImageHeight, Boolean ImageDisplay, Int32 Location, Int32 Category, String Reminder, Int32 TimezoneOffset, Boolean SendReminder, Int32 ReminderTime, String ReminderTimeMeasurement, String ReminderFrom, String CustomField1, String CustomField2, Boolean EnrollListView, Boolean DisplayEndDate, Boolean AllDayEvent, String CultureName, Int32 OwnerID, Int32 CreatedByID, Int32 UpdatedByID) at DotNetNuke.Modules.Events.EventRecurMasterController.EventsRecurMasterSave(EventRecurMasterInfo objEventRecurMaster) at DotNetNuke.Modules.Events.EditEvents.UpdateProcessing(Int32 ProcessItem) at DotNetNuke.Modules.Events.EditEvents.updateButton_Click(Object sender, EventArgs e)

Anyone any ideas of what might be wrong? (and how I can correct this).
