I had this issue for many years and on various different hardware platforms and various MP1 versions and also various MySQL / SQLExpress versions. And I've reported it over and over again. It happens with MySQL more often than with SQLExpress but none of them were reliable. I figured out a workaround by starting SQL and TV server with a batch instead of automatic, but I needed to add a delay of some minutes!!! between SQL start and TV server start to be on the secure side.. This never get fixed and was a major one of the many reasons why I don't use MP1 any longer. In the two years I'm now using MP2 with SQLite as Database this never ever happened again.Note that to the best of my recollection you're the only person who has ever reported experiencing this problem.
It's a long time ago, but I'm pretty sure I have even uploaded the batch file somewhere here in the forumdid you perhaps report that you had created that batch file?
Okay.the recordings were supposed to be yesterday, 14 November around 8:30 PM
