You might want to give us the EXACT error message, word-for-word, verbatim.
Please also clarify what you mean by "upload" as there really is no function named "upload" in Lightroom. What is the name of the Lightroom function you are using?

If the message says something else, let us know.

Most likely, these two different messages indicate that the folder where the photos are supposed to wind up does not have WRITE permission. So change your permissions.
By the way, when someone asks for the EXACT error message, we don't really want you to tell use the error message was "something like..."
