To cure this we added the JSON classes from the jsonObject.class.asp file to the incfunctions.asp file so if you get a new copy of the updater and apply that it should fix it all.
Hi Sparksm In the new copy of the file vsadmin/inc/jsonObject.class.asp in the updater there should just be a comment that the file is left intentionally blank. Can you make sure that's the case and that you copied the file to your server to the correct location?
