Already tried to re-install the studio, but it's still not working...

Same problem here. Did you find a solution?

Hi Randy, if you get this issue, there may be a problem with your security settings for IE, also try adding that site to you compatibility view under the Tools tab in IE. This should solve your problem. You also want to be sure that the StartPath property of your WebApplication is set to a url so that the bot knows what page to load and where it should begin its interrogation.

Hi Nia,

Thank you for your response, may I know if what particular security setting i should change in IE?

Yes, Randy, the settings would really depend on your current IE settings, however, the quickest way to see if this is in fact the issue is to open internet options of IE and change the Security settings. Enabling more options seems to usually help.
