Car wont stay running - again

[mfinos]

Loaded the 93 tune newest version trinity tune in my 2011 300C. One day later engine light comes on. loaded original tune back immediately. Now car barely starts but wont keep running. This happened to me last November when I first used the Trinity with a much older version. I cant believe that after I upgraded to the newest version that this problem could still exist. Both times on a Saturday, no car until Monday when tech service is open.

Has anything changed where I can reset myself, or do I have to wait until Monday?

I am quickly losing my faith in this product.

if the cel came on a day later, it was not related to the tune.

check and clear the code, if that does not help, try disconnecting the battery for a minute.
