Game locking up on me.

Since the last update, I'm having this really annoying problem:
The game locks up on me, with nothing that I can do. Mouse is active and movable, music is still playing, cable modem still blinking (As in still transferring data), but the game, is "dead". I tried to ALT + F4, ALT + TAB, ALT + ESC and ALT + ENTER to try to quit/minimize/resize, but nothing. All I can do, is restart manually the PC to quit the game.

Here. I took a video with my camera phone to show the problem in action (Sorry, no sound): http://www.youtube.com/watch?v=61v6-_zLe30

Is there something that can cause this problem that I can try to fix, or something? It's really annoying and probably will be sad, when it will lock up in some important/good part of the game (Good drop, PVP fight, middle mission and such).

Most Cable Broadband systems are shared ,there is a constant transfer of data as long as the up and down links are established, just because your modem is working on your internal network does not mean it is getting the data to and from the location that you are trying to reach.

The Red status Indicator in your video would seem to suggest a spike in packet loss or latency. In order to remove the possibility of connectivity issues, you should run guildwars with the -diag switch.

Goto start > run

Then enter

"C:\Program Files\Guildwars\gw.exe" -diag

This should output a log file in your guildwars folder. Take a look at the connectivity information, maybe post it here along with the rest of the information from the file. Make sure you have updated your drivers and direct x release to the most current release.

The mark was orange , not red. But even if it would be red, it would be still possible to move the camera around, click on buttons or even ALT + F4 out of the game. In my case, I couldn't do any of the things.

And here's the connectivity results:
