Picking up some errors
Installation and Configuration
Try running the INTEGRITY CHECK to fix the play_key error, go to:
ACP -> CORE -> SYSTEM CORE -> TOOLS -> INTEGRITY CHECK
check all the checkboxes, then START.

The second one is just a warning, its saying that for some reason the process that fires every minute couldnt complete on one particular minute. But thats ok, because the process that fires the next minute will pick up any left over tasks that were queued and do them.
