hello, first please make sure that the date, time & timezone are set correctly set correctly on your system. if this doesn't solve the issue (or it is already set properly), a solution depends on the individual circumstances:

  • what is the error code shown when you click on advanced on that error page?
  • please also give us more information about the error by clicking on the error code, copying the text to the clipboard and then pasting it here into a reply in the forum.

thank you!

What do you mean with usertesting ?

Is that something that appears in the Windows Control Panel ?

That could very well be possible if you do not remember that you installed this software yourself.

You can do a Google search for software that you aren't sure of to see what it is about.
