Level Editor Crashed

[Janni1234]

Hi,
I took the infected from a custom story and experimented a bit in the model editor.I forgot to make a folder and put my enemy in Redist/Entites/enemy.
Now, i wanna open the enemy folder in the level editor and the editor crashes.
I think i had to make a folder for the infected.I deleted the whole enemy folder and made a new one, copied the enemys on my destop,created a new enemy folder and dragged the enemys back in the enemy folder.
It still doesn't work.When i go back to the model editor and click "open"
and go to the enemy file, i can see my infected.ent (the model i created)
Is there any way to delete him?The .ent file is not displayed in my folder, if i'm not in the editor.
i really need some help
