I have the same BlueSoleil popup issue as well. I have an HTC HD7 Windows Phone 7.8. BS 10.0.457, RR June2013. It's happened with all the version of this plugin that I've tried, 101, 103, 104 & 107. It pops up shortly after the phone connects.
I have another question.How do you handle the phone not being available to connect? If I don't have the phone within connection range after about 5 to 10 minutes I get the error message "RiderRunner encountered an error and needs to close." It only happens if the phone is not in connection range and has happened with all the plugin versions I've tried. It's never happened when the phone is connected but I won't have the phone available to connect 100% of the time.
