yea that's due to ATV's auto timer plugin. Their latest version doesn't like autotimers/recordings that are on the same time. Grogbuild FreeRange comes with an earlier version that handles them fine but by doing a software update you have installed the latest version which is BROKE. For most people the broke version is probably fine but for those that do a lot of multiple recordings it's no use
I always say don't bother with software updates. Basically you have three options:
1. edit your timers so they don't clash, ie using +1 channels etc
2. find version 4.3.1 of the Autotimers plugin and install that.
3. reinstall grogbuild freerange, probably takes no longer than doing software updates and don't do software updates
