I've been digging through this forum and see that a lot of people have had problems with the Source SDK being broken recently and I've seen a lot of fixes for people to get mapping again for games like CS:S but I can't find any info for people having trouble with the CS:GO SDK.

Basically, I can launch it just fine but when I go to boot Hammer, I get an error saying:

"Setup file 'gameinfo.txt' doesn't exist in subdirectory
'D:\xxxdirectorypathxxx'

I looked in the directory it points me to and the file is right there! Refreshing the SDK content isn't an option as that button doesn't exist on the CS:GO SDK like it does on the Source SDK.

Any suggestions? :)
