Server issues (Involves: Nexus/Skeleton)

Hiya, I’m having a bit of a problem with my Dev server, whenever I try to load up any mode for Nexus or Nexus in general or just ANY gamemode besides the ones that are already installed on the server will not load up. If I could get help I’d really appreciate it (I’m not sure but I think I may have a leaked version of Nexus or an older one).

Your server will keep crashing, delete these two files, sourcenet.dli and also gamedescription.dli, hopefully it should work.
