Firstly, if this is an extreme show stopper that is costing your company a lot of money for downtown, I would definitely reccomend using our support line and calling in. However, hopefully it is not that awful.
Have you tried this on multiple computers, or just your one?
This happens with every new project you create?
When you open LabVIEW again, does it give you a crash report?
Is it just network, or all shared?
When does the window with the broken arrow appear? Is it possible for you to post a screen shot of that window? When you say you cannot create a real time project, do you mean it throws an error? Can you open an existing project?
