If you had Skell's mathack installed prior to the update you need to re-install it, yes it still works, no valve didn't break it. no it doesn't need to be updated.
Hopefully this will stem the flow of "update ploq" posts.

Update 108 was pushed a couple days ago.
With its small number of worth-while changes it updated a couple .vmt's, scout_red and ubersaw.
I have attached the updated files, and all of the c_items .vmt's.
They have been edited to include the $ignorez variable and scout_red uses models\player\red.vtf.
The paths are all correct. These are only the files that were updated in patch 108.
Maniac/Vash/Red could virus scan these if they like, but I don't think a handful of .vmt's are dangerous.
