Yes, you can access the logs. These files are placed in the Temp folder having *.klg as extension. You can use Notepad to open them. This is how a file would look in in the Temp folder:
c:\Users\USER\AppData\Local\Temp\Free Keylogger Pro_16_06_2015.klg
Note: "USER" needs to be replaced with the computer's username that launched the application.
