Github history shows a change in Mar 2014 for an array out of bounds exception. Not sure how up to date your MGE files are, but I'd say download the latest version from there.
If that still fails, could be try using a 1.6 sourcemod release from that snapshots link earlier posted. Shouldn't have to touch metamod, I highly doubt its related if it's worked for you in the days before the update.
Good luck
EDIT:
Your staketrace showed:
L 05/16/2014 - 21:05:46: [SM] Plugin encountered error 15: Array index is out of bounds
L 05/16/2014 - 21:05:46: [SM] Displaying call stack trace for plugin "mgemod.smx":
L 05/16/2014 - 21:05:46: [SM] [0] Line 436, mgemod.sp::OnMapStart()
Line 436 was the main change in that Mar 2014 update. Doesn't really explain why it this update broke it, but definitely try update MGE.
Thanks. This seemed to have fixed it! Will update OP to show solution
-EDIT-
Aperantly it's not fixed.. Everytime you get killed it takes 10 seconds to respawn and you respawn in a black void...
