Programme log

Hello,
I have loaded the latest version of MFP and now I can't access the log files.  When you  click on programme logs you get a message saying 'undefined'.  Obviously I have checked the wrong box or something similar along the way.  I have tried reloading but still the undefined message.
Any ideas on what I have done and how to correct the error?
Kind regards,
Tony

Try clearing your old logs and restarting the program. You can do so by manually deleting the "logs" folder in the following path:

c:\Users\%username%\MarketFeeder Pro 7\profiles\%profile name%\
