I downloaded and installed 10.0.3, and I am no longer getting the error messages.
An old problem has come back I'm afraid. When I go to Add Layer(s) for a map it takes quite literally 6 minutes to search, and then none of the aerial photos that I have saved in the Trimble come up. I go to Advanced Settings>Extensions and there are no problems there. The aerial photos are saved as jpeg2000, and that extension is there and checked.
