ddouglas,
Apparently I misunderstood your question about unistalling. Yes. I always unistall the old version (of Hoster or Microstudio) before installing the new.
When I asked how, I thought you were referring to the old version of firmware.
I thought maybe I was supposed to unistall 1.09 before upgrading to 1.10. However, I will try removing and installing the program again if you think it might help.
Thanks,
Kelly
