The last two days it is giving the wrong about of hours played. it i alway more then I really played. After a hours it says i have been playing for 3 hours. How can I fix this ?

Exactly which stat are you using, and which report are you using? If you want to look at real time played you need to use the appropriate "Real Hours X" stat for the type of report grouping you're looking at - for example if you're looking at a report split up by day then you need to use "Real Hours Date".

I don’t use reports but i am watching the hours on the result part
like this : month/ my c won/hands/ etc…/hours

So are you looking at Results > Overview?
If you're using the default report and it gives the wrong data please attach the hand history files for the session to a Support Ticket along with a screenshot of the problem so that we can investigate.
By default the original hand history files will have been moved to the Processed folder, which you can access via File > Open User Data Folder in the PT4 menu.
