[chirp_users] Can't upload

Good evening, I can't seem to upload to my UV5, I have CHIRP on an XP machine, I have downloaded the channel info from my UV5-RE 293.

From the help menu  I have listed versions GTK 2.24.10 PyGTK 2.24.0 Python 2.7.2 When I try to upload, the radio type & file type buttons are grayed out, can't be changed. Thanks for you help, Tom
