Vista Tutorial - World of Warcraft Connection Issue

I've recently updated my drivers (mainboard, network card, and graphics card) and for some reason I am unable to log into WoW with 3 of my 4 characters. I can log in with my rogue just fine and run around, but as soon as I try to log in any other character (warrior, druid, or DK) I'm instantly disconnected from the server as well as from my home network. The only fix is to restart the computer so I can get back onto the network. I've tested removing all addons, deleting the WTF, Cache, and Interface folders. I've done a repair using the Blizzard repair .exe and I'm still only able to log in using the rogue. I have two desktops and a laptop at home and I don't have a problem playing the game on any character using the other desktop or the laptop. I'm pretty sure there is some sort of corrupted file for WoW in my system and I'm wondering if there is a fix other than reinstalling the entire game. The fact that I can play as the rogue makes me think it doesn't require an entire reinstall. Any ideas?

not sure on this cause i don't play but does the game keep your characters on the HDD at all or no? if so can you copy from your other computers?

you might just have to do a re install on that computer

I'm not sure to be honest, but I did a complete uninstall and reinstall of the game last night...still can't load up as any other character than my rogue.

/sigh

will talk with me buddy that plays later today and see if he has any ideas.

Talked to my buddy, he also once had this issue.

The solution is to contact WOW (your user data is corrupt for those characters) as all the info is stored on there end and not yours.
