I'm using tsplus since the ts traveler version and i enjoy it

On one windows 10 pro, i installed tsplus system version and it was working perfectly.
But, last week, when connecting remotely, i saw 3 black flashing windows and then the connection cuts of automatically.
I can reconnect right after but the problems remains the same : these flashing windows, and the deconnection.
I restarted the server and it helped but the problem is coming again today.
I got this problem an another computer about 6 months ago and i formated the computer as it was easier and faster to do...
But this time, it is not possible to format it so i need to fix it.
Anyone got an idea? else, i will reinstall the tsplus software but i d prefer to fix it to avoid to get the same problem later.
Thanks !
