Problem communicating with GPSMAP 62s

Hi guys.
I use a much older version of basecamp, and while I was downloading that I also downloaded the latest software for my sixty two series – (I'm on a keyboard where the "two" isn't working!).
I can't get rid of this error message that’s why I've downloaded and removed basecamp twice:

Error
There was a problem communicating with GPSMAP 62s (Unit ID 3813189875) (E:) An error occurred while reading the following file(s)
E:/Garmin/gpx/imported_29-DEC-10 040952 AM.gpx
Any cure? Thanks in advance.
