Issues with missing parameters and partial connection.

Stem and my brother got all of our graphs and parameters setup in the scanner and when we went to tune this morning we were suddenly having an issue where parameters were all hit or miss. Meaning that upon connecting a majority of our parameters were broken and not working. After re polling it made no difference. We unplugged and plugged back in and about half started working but other were not able to be added or found under add. For example we never could get injector duty cycle up. The previous day we had 0 issues like this and 0 issues connecting. Today sometimes when there were no parameters when I would click darters it would give a message saying needed to connect but I was connected according to the icon and it would let me read DTCs and such. This combined with wideband issues blew away most of our time today.
