eLicencer Control-Error message panel stacked

Message as follows is displayed and continues to exist,
and clicking to abort nor changing USB-port does not work.
So I cant’t it clear without restarting my machine.
How to clear it by manual?

There is an USB communication problem…


  • Click to abort.

When the error pops up, try switching to a USB2 Port, not a USB3 Port. After switching, click on OK to proceed. Does this help?

Thank you, music. I will try your suggestion when that happens again.
I tried switching to another port on the same USB HUB in vain!
