Thanks for your responses!
Flag - Cheers yeah that explains what I was wondering. I will change it to 5 when it lets me without the error.
Firmware of Console is 212 and version of WL is 5.9.2.
I have tried setting it seperately yes, Setup > Set Archive Interval with the same problem remaining.
John - Okay, I have clicked 5 minutes, error message appeared, now going to Browse the Station Data to see what increment is now being used.
Dalevoy - Yes John knows it the USB connection I am using, as it was him that sold me the setup (brilliant service). No other weather software installed.

James
