Help my data logger is not working right?

I have a Lacrosse data logger ws2010-13, which is suppose to capture data from the ws 2010 weather senors. Well it does a good job with all the senors except for the outdoor temp. The senor is no more than 15ft from the data logger. How do I get the data logger to get the signal? The base station is has always gotten a signal from the outdoor sensors with no problem at all.

hi
some things to try:
remove the batteries, then re insert
then dont use any software to access the data logger for at least 15 minutes, to let it resync up
also, move the data logger as far away from the pc as you can, and even put a RF balun around the serial cable, or even extend the serial cable
those things should help
but in weather display, make sure you have selected the outdoor sensor number to use as normal station temperature (i.e 1 )
