Wonder if anyone can help.  I've just registered / Activated my copy of ACAD LT with Autodesk and am now using the programme.  I also got a confirmation EMAIL from AutoDesk to confirm this.  However when I try to download the patches available through Communication Centre I get the following error message.  The suggested remedy does not work.  The same message appears next time I try.  Grateful for any assistance
