I should most likely contact Steam Support as well about this, but my hope is this will be an easy fix.
My friends and I recently purchased Insurgency, so, in an attempt to get a server running, I downloaded SteamCMD, set the installation directory, and ran
app_update 237410 -validate
Unfortunately, for whatever reason, SteamCMD failed to complete the download and gave me an error
Error! App '237410' state is 0x10502 after update job
This was all done on my server machine which is currently running CentOS 6.5 64 bit. Does anyone know what would cause this error?
