If you are going to do this please everyone, post ALL OF THE NECESSARY INFO so that we can look into the issues. Meaning:
What device are you using
Year/make/model and strategy of vehicle you are logging
What is the firmware revision on it
What version of livelink are you using
What operating system is on your computer
I will say that a new version of livelink is being released within the next 2 days that addresses MANY issues stability wise with the software and adds some new features. Problems with the SVT have not been addressed but I already have them looking into the issue.
