Errors in my App after installing 9.50

I downloaded the updated version today (thanks!) and everything installed just fine. When I recompiled my project so it would implemet the 950 version, I am now picking up errors in the compiler. I was wondering if you could tell me how to fix this error. What I get for an error message is:

error C2385: 'CXTTreeCtrl::GetNextItem' is ambiguous
warning C4385: could be the 'GetNextItem' in base 'CTreeCtrl' of base 'CXTTreeBaseT<class CTreeCtrl,class CXTTreeBase>' of class 'CXTTreeCtrl'
warning C4385: or the 'GetNextItem' in base 'CXTTreeBase' of base 'CXTTreeBaseT<class CTreeCtrl,class CXTTreeBase>' of class 'CXTTreeCtrl'

My function is as follows:

HTREEITEM CPaneEngineParameters::GetFirstCheckedItem(void)

{
   CXTTreeCtrl* pTreeCtrl;
   for ( HTREEITEM hItem1 = pTreeCtrl->GetRootItem();
      hItem1!=NULL;
      hItem1 = pTreeCtrl->GetNextItem( hItem1 );
   )
   if ( IsItemChecked(hItem1) )
      return hItem1;
   return NULL;
}

Thanks.
