The problem was the google chrome directory. You can only make one chrome session with that chrome directory. This should because of the file SingletonLock, this prevents me to create multiple session with the chrome directory. So I did a work around before I use the chrome directory, I simply copy and give a time-date stamp at the end of its name. The copied folder should be in the same folder as the original one. Then I use the chrome directory to make chrome sessions. Once I am done. I simply replace the original chrome directory with copied one but keeping the same original name. This way I can make many sessions as needed. And the cookies are not lost I have kept one profile for one directory.
