Instant update for my addon ? And instant download ? (30MB)

Hi, i tried to update my addon but the problem is that upload of the update (30Mb) is instant, no error.

I already had this problem but it was because there was invalid file format.

Here is my addon (folder) http://extrem-team.com/ws.rar

Error in gmod :

h:/steam/steamapps/(username)/garrysmod/garrysmod/addons/grymod_2.4_|_a.k.a_crysis_in_gmod_105039232.gma

I also do have instant downloading problem… I can’t reinstall addons
