I am sorry but could you please write you're post down in english next time! The thing is that if you have a free licence of teamviewer you can only connect to a pc for 3 hours after that it shuts off. If you would like to be longer connected you need to buy a teamviewer licence. I know this is a very very late response but i hope you know it now!
I hope this helps.
Thank you for using teamviewer!
