Hmmm--I didn't think LW would still offer Pro for OS 9, since they stopped supporting it quite a while ago.

The internal problem message can probably be ignored, but restarting your Mac is probably a good idea.

The connecttion problem may indicate that you got connected to some bad ultrapeers. The awkward workaround is to use the File->disconnect, then Reconnect menu items, and hope you connect to some better ultrapeers.
