I can't activate draftsight since I keep getting a proxy error.  My IT guy says it's because the Draftsisght license server is being blocked by our web blocking software but he can't unblock it without knowing the specific URL.  I had this exact same problem with another piece of software and once we found out the url we unblocked that site and activation was flawless.  If any one knows the specific URL that Draftsight attempts to ping to check the license please let me know so I can have my IT guy unblock access to this site.
