This issue has been caused by changes to Bentley’s website.
To avoid it:
1. Close gINT.
2. Open Task Manager > Processes / Details and kill any gINT8 processes.
3. Then do one of the following:
i. Clear cache in Internet Explorer
ii. Open gINT and immediately check the “Hide web browser” check box, do this before the error appears. If your internet connection is too fast then try disabling your network/internet connection temporarily.
