Hi All, after searching various reviews, community s and you tube vids I decided to plunge in and get a used vci-100 from ebay. I have a few questions I need to ask and a few problems I hope you can help to solve.

How do I find out what firmware my vci is running?

When using Traktor 3 LE sometimes the midi is set automatically to the vci but sometimes it's not and I can't select it manually.

When using Traktor Pro 1.2.4 I can't make the midi settings save so they revert back to keyboard even though the icon on the player show the midi is connected. A fresh install sometimes solves this but as you can imagine I don't want to re-installing Traktor.
