Problem med att skicka färdiga WU

Hej,
Av någon anledning så kan jag inte längre skicka WU till servern. Någon som vet vad det kan vara för fel?? Här är ett utdrag av vad som står. Jag har testat att starta om datorn och använda -send x med olika WU nummer, men det funkar inte heller. Kan det vara nån brandvägg som börjat blocka, det går att pinga servern iaf.

Okej, men windows Update körs inte just nu i alla fall. Hur gör jag för att få igång sändningen, antar att vissa av mina färdiga WU's "går ut" snart.
