The error prompts may have been pictures that were an unsupported format, or possibly files that weren't pictures.
Is the list populating in the PC Share Manager share window at all?
I found many threads on the PC Share Manager, but I didn't see anything on my particualar problem.
Originally installed ok, mistakenly tried to share entire picture folder. Progress bar was advancing, but it was taking forever, so I let it run all night. In the morning, there were a few error prompts, though not sure what they were. Blu-Ray didn't find antything, so I uninstalled it, and re-installed it. Now, trying to chose smaller folder to share, noting is happening. No progress bar, nothing.
