I've already looked at this instructions and added the firewall and disabled antivirus but same results.

Did you change the time on your computer?

No i didn't

Did you setup the license on more than 1 computer? If so, you should deactivate the license on one computer before activating it on another computer.

If the issue persists it is better if you can contact us through our contact form, mention this Forum thread and provide your license code:

I did try it on the second computer after it wasn't working on this computer. But when i want back to this one I disabled it there. One thing I found is that if I launch RoboDK in safe mode and put in the license and try to save a program it will work.

I think I found the solution, atleast it's working for now. Under AppData\Roaming\RoboDK there are settings.ini and settings_3.3.0.ini. If I deleted them it made new ones on the first launch of RoboDK and there were no license errors, but when restarted they were back.

So after some trying I found out that when the settings_3.3.0.ini is restored it will give the licesne error. So I deleted the content of it, made a file read only and now it works. I don't know how good this solution is and what will be the side effects but for now it seems to work.
