Simplify3D 4.1.1 will not start up again.
After start-up problems in December it worked fine for a few weeks.
Now the problem is back again.
At start a pop-up appears "Connection to Server Failed"
Un-install - re-install - install older version firs, nothing helps.
Version 4.1.1 can't be started-up anymore.
Internet connection is working fine, so what can be the problem?
