1GB RAM
cameras: Canon 20d, Canon PowerShot SD950
When I plug my camera into my computer by USB cord PM launches and opens, but the ingest window doesn't open. When I go to File, then Ingest the window opens, but my camera is not listed in the Source Paths so I am unable to upload the photos from my camera.
