GMOD 13 Glitch HELP!

Okay so i have been playing GMOD forever <3 I Love It so much, So you’d think when GMOD 13 came out it would be awesome right? Well Kinda it worked fine until i used ADDONS to add
Something called “WW2 german NPC’s” it started downloading it took about 4 hours until it was done… Then i tried to download something else… AND it started to still be downloading the NPC’s and every time i close GMOD it just restarts and it wont go away, Its starting to annoy me and i need it gone any ideas?
THANKS :smiley:

P.s : My Tools have had their names changed glitch or update?
P.P.s My chat has also changed Glitch or Update?

Thanks :smiley:
