Plugged in my Tactrix today to download yhe tune and to look at fuelling. The tune is one that I've done myself and uploaded about 8 weeks ago.

Same cable same software, is nothing has changed.

Downloaded the tune, did my changes and now its not allowing me to upload? Test write webt fine but not the real one.
