To add to the info here ...

Disabling my router firewall also worked.

The security log shows that it was being blocked as it was recognized as a "TCP FIN Scan".

I won't be using Curse at all until this is solved - disabling my router firewall is completely unacceptable.

It would help us figure out the issue if those of you who got it working by disabling your firewall would post the make and model of the router you are using, and possibly any relevant settings.  We certainly don't expect everyone to run unfirewalled just to use the client.

My fricken addons dont evem show up when i log into wow it dosent show the little box next to the charachters.

I have a Belkin N Wireless Router ver. 3100 

The firewall for this router is either "enabled" or "disabled", so unfortunately I cannot provide further info as to settings as far as I know.

Hi Prodigal

SMC 7004ABR EU V.2 (Hardware Version o1)

Firmware 1.015

Firewall Settings:

    *  Intrusion Detection Feature

      SPI and Anti-DoS firewall protection :   on 
      RIP defect :     on
      Discard Ping To WAN : on    

    * Stateful Packet Inspection

      Packet Fragmentation     on
      TCP Connection     on
      UDP Session     on
      FTP Service     on

      H.323 Service     on

      TFTP  Service     on

    * Connection Policy

      Fragmentation half-open wait: 10 secs
      TCP SYN wait: 30 sec.
      TCP FIN wait: 5 sec.
      TCP connection idle timeout: 3600 sec.
      UDP session idle timeout: 30 sec.
      H.323 data channel idle timeout: 180 sec.

    * DoS Detect Criteria:

      Total incomplete TCP/UDP sessions HIGH: 300 session
      Total incomplete TCP/UDP sessions LOW: 250 session
      Incomplete TCP/UDP sessions (per min) HIGH: 250 session
      Incomplete TCP/UDP sessions (per min) LOW: 200 session
      Maximum incomplete TCP/UDP sessions number from same host: 10
      Incomplete TCP/UDP sessions detect sensitive time period: 300 msec.
      Maximum half-open fragmentation packet number from same host: 30
      Half-open fragmentation detect sensitive time period: 10000 msec.
      Flooding cracker block time: 300 sec.

I found a Solution that works (for me) without disable the Routerfirewall.

The Problem was:

 Maximum incomplete TCP/UDP sessions number from same host: 10

after increasing the numbers of incomplete TCP/UDP Sessions up to 50 the Client works fine.

New Client version (3.0.0.5)

Same Problems, no reaction since nearly 3 weeks.

Sorry but i'm not able to fix the Problem for curse!

Your previous post indicated that you were able to make it work with your setup.

Is there another issue you are having now with 3.0.0.5?

Ive been having the same problems as all of you, however disabling my firewall security was not an option. Then I realized I hadnt updated my routers firmware in over a year. Updated it, and Curse updater works fine.

client version 3.0.0.5 at time a addon have on curse a updatet addon that are download but the client download the addon not .

The message download faild but at version 3.0.0.3 -4 have i that problems not .

Prismatech - Am I understanding correctly that it worked in 3.0.0.4 and is now having a problem downloading in 3.0.0.5?
