Crash when placing an entity

[RedMser]

EDIT: silentstriker didnt make a tutorial; he rather just uploaded a fixed version.

heres the thread

If I use it in a CS, do I have to put it in the folder with the CS or is it just in the editor and it works ingame without fix?

EDIT: Did like the instructions said and it worked, thanks!
