You are probably looking at the wrong log
Click on the "Experts" tab and then right click inside the tab and then "open"
It could be that that what you have printed is kept in the RAM. Normal files you can flush (FileFlush()) so save everything immediately.
But Print(..) can't do this. But you are lucky you have three different options:
1) kill the terminal and restart it,
2) flood the log by huge amount of Print(..),
3) wait until the next day - the logs are closed and a new one for the new day is opened.
