Been getting this alot lately after updating my server and restarting
im not to sure but i think i have gotten this with rcon lock as well
my guess its a bug with sm?
maybe reinstall fresh copy sm?

Error in file transmission I'd guess.

Re-download KAC. KACSM/1.2/kigen-ac-pub.smx

uploaded fresh copy sm ,
sockets, sdkhooks.ext
reinstalled KAC plugin
manualy
logging no errors now

I was sweating bullets without KAC
it's the best thing next to sliced bread

I would not play in a server without it
my next check im going to open my
wallet
keep up the good work
Thanks
