This just happened to me yesterday. All of a sudden I could not join any of my teamwork projects. After hours of frustrating trial and error, I found out that when I uninstall the Cadimage tools, there is no longer a problem.
I opened a support ticket on Cadimage website, so I will see if they have a solution.
BTW, I'm using 3006 USA, and (was using) Cadimage design suite 30 day trial.
