So you were ok with one file worked with remote access. Sounds like the issue I have with multiples.
As for access via LINK you may have to check to insure it sees the computer if your talking about local connection. I have not had issues with local connections.
When your device is connected to the same Wi-Fi network as your computer, you can sync your music, pictures, videos, and documents. You can also access your files from your device. For information about how to connect your device to a Wi-Fi network, tap the Help app on the home screen of your device.

By default, BlackBerry Link allows Wi-Fi connections. If your computer doesn't have a Wi-Fi network or you don't want to allow Wi-Fi connections to BlackBerry Link, you can turn off this feature

make sure it is not off
